Introduction Ecma Technical Committee TC31 was established in 1984 for the standardization of Optical Disks and Optical Disk Cartridges (ODC). Since its establishment, the Committee has made major contributions to ISO/IEC JTC 1/SC 23 toward the development of International Standards for optical disks. Numerous standards have been developed by TC31 and published by Ecma, almost all of which have also been adopted by ISO/IEC under the fast-track procedure as International Standards. The following Ecma Standards for DVD 120 mm and 80 mm have been published by Ecma and adopted by ISO/IEC JTC 1. Those standards are based on original specifications from The DVD Forum. ECMA-267 (2001) 120 mm DVD-Read-Only Disk, 3rd edition ISO/IEC 16448 ECMA-268 (2001) 80 mm DVD-Read-Only Disk, 3rd edition ISO/IEC 16449 ECMA-272 (1999) 120 mm DVD Rewritable Disk (DVD-RAM), 2nd edition ISO/IEC 16824 ECMA-273 (1998) Case for 120 mm DVD-RAM Disks, 1st edition ISO/IEC 16825 ECMA-279 (1998) 80 mm (1,23 Gbytes per side) and 120 mm (3,95 Gbytes per side) DVD-Recordable Disk ISO/IEC 20563 (DVD-R), 1st edition ECMA-330 (2005) 120 mm (4,7 Gbytes per side) and 80 mm (1,46 Gbytes per side) DVD Rewritable Disk ISO/IEC 17592 (DVD-RAM) 3rd edition ECMA-331 (2004) Case for 120 mm and 80 mm DVD-RAM Disks, 2nd edition ISO/IEC 17594 ECMA-338 (2002) 80 mm (1,46 Gbytes per side) and 120 mm (4,70 Gbytes per side) DVD Re-recordable ISO/IEC 17342 Disk (DVD-RW) ECMA-359 (2004) 80 mm (1,46 Gbytes per side) and 120 mm (4,70 Gbytes per side) DVD Recordable Disk ISO/IEC 23912 (DVD-R) In April 2007 nine members proposed to TC31 to develop a standard for 120 mm and 80 mm dual layer DVD Re-recordable optical disks using Phase Change recording technology and TC31 adopted this project that has resulted in this Ecma Standard. This Ecma Standard specifies two Types of dual layer Re-recordable optical disks, one (Type 1S) making use of recording on only a single side of the disk and yielding a nominal capacity of 8,54 Gbytes for a 120 mm disk and 2,66 Gbytes for an 80 mm disk, the other (Type 2S) making use of recording on both sides of the disk and yielding a nominal capacity of 17,08 Gbytes for a 120 mm disk and 5,32 Gbytes for an 80 mm disk.

This Ecma Standard has been adopted by the General Assembly of December 2008.

Scope This Ecma Standard specifies the mechanical, physical and optical characteristics of a 120 mm and an 80 mm dual layer DVD Re-recordable disk to enable the interchange of such disks. It specifies the quality of the embossed, unrecorded and the recorded signals, the format of the data, the format of the information zone, the format of the unrecorded zone, and the recording method, thereby allowing for information interchange by means of such disks. This disk is identified as a DVD Rerecordable disk for Dual Layer (DVD-RW for DL). This Ecma Standard specifies: − 120 mm and 80 mm nominal diameter disks that may be either single or double sided; − the conditions for conformance; − the environments in which the disk is to be operated and stored; − the mechanical and physical characteristics of the disk, so as to provide mechanical interchange between data processing systems; − the format of the embossed information on an unrecorded disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method used; − the format of the data and the recorded information on the disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method used; − the characteristics of the signals from embossed and unrecorded areas on the disk, enabling data processing systems to read the embossed information and to write to the disks; − the characteristics of the signals recorded on the disk, enabling data processing systems to read the data from the disk. This Ecma Standard provides for interchange of disks between disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems.

2 2.1

4.10

Disk Testing Area (DTA) The area used for Optimum Power Control. There are two kinds of the Disk Testing Area on a disk. Inner Disk Testing Area (IDTA) is located in the R-Information Zone and situated adjacent to the inside of the Recording Management Area. Outer Disk Testing Area (ODTA) is fixed and situated adjacent to the outside of the fixed Middle Zone. The optional IDTA can be located on Layer 1 facing the special allocation in the Initial zone on Layer 0 as an option for devices, when NBCA is not applied on a disk.

-2-

4.11

ECC Block address The absolute physical address used to define the recording position on the land of each area. This address is pre-recorded as Land Pre-Pits and equal to the bit-inverted numbers from b 23 to b 4 of the Physical sector number recorded in the groove. Serially decremented numbers are assigned to blocks from the inner radius to the outer radius on Layer 0 and from the outer radius to the inner radius on Layer 1. The first ECC Block address in the Data Recordable Zone on Layer 0 is (FFCFFF). The bit-inverted number is calculated so that the bit value of one becomes that of zero and vice versa.

4.19

Land Pre-Pit (LPP) Pits embossed on the land during the manufacture of the disk substrate, which contain address information.

4.20

Layer jump address The address on Layer 0 that causes layer jump to Layer 1. The end sector number of the Data area on Layer 0 and the address that is located immediately before the shifted Middle area are also Layer jump addresses.

4.21

Lead-in Zone The zone comprising Physical sectors adjacent to the inside of the Data Zone on Layer 0.

4.22

Lead-out Zone The zone comprising Physical sectors adjacent to the inside of the Data Zone on Layer 1. -3-

When the recording of user data is finished on Layer 0, the Lead-out Zone is located adjacent to the inside of the Middle Zone on Layer 1.

4.23

Middle Zone The zone comprising physical sectors adjacent to the outside of the Data Zone on Layer 0 and Layer 1 respectively. The fixed Middle Zone is located outside of Data Recordable Zone of a disk. The shifted Middle Zone can be added between the end of the Data Zone and the start of the fixed Middle Zone as an option for devices, depending on the size of the Data Zone.

4.24

Recording Management Area (RMA) The area containing the Recording Management Data (RMD), situated adjacent to the inside of the Lead-in Zone on Layer 0 and the Lead-out Zone on Layer 1 respectively.

4.25

Recording Management Data (RMD) The information about the recording on the disk, including information for recordings. Two kinds of RMD format are specified. Format2 RMD contains the information of Pionter to indicate the valid Format3 RMD Set in the RMA segment. Format3 RMD contains the information related to Restricted Overwrite recording mode including Layer jump recording mode.

4.26

Restricted Overwrite Recording mode which realizes to record the ECC block(s) onto any portion of recorded ECC block(s) or, to concatenate the ECC block(s) to the most outer recorded ECC block(s) with the Linking scheme.

4.31

Track A 360° turn of a continuous spiral of recorded marks or groove.

4.32

Track pitch The distance between adjacent average physical track centrelines of the wobbled grooves for the unrecorded disk, or between adjacent physical track centrelines of the successive recorded marks for the recorded disk, measured in the radial direction.

4.33

Zone An annular area of the disk.

Conventions and notations Representation of numbers A measured value is rounded off to the least significant digit of the corresponding specified value. For instance, it implies that a specified value of 1,26 with a positive tolerance of + 0,01 and a negative tolerance of - 0,02 allows a range of measured values from 1,235 to 1,275. Numbers in decimal notations are represented by the digits 0 to 9. Numbers in hexadecimal notation are represented by the hexadecimal digits 0 to 9 and A to F in parentheses. The setting of bits is denoted by ZERO and ONE. Numbers in binary notations and bit patterns are represented by strings of digits 0 and 1, with the most significant bit shown to the left. Negative values of numbers in binary notation are given as Two’s complement. In each field the data is recorded so that the most significant byte (MSB), identified as Byte 0, is recorded first and the least significant byte (LSB) last. In a field of 8n bits, bit b (8n-1) shall be the most significant bit (msb) and bit b 0 the least significant bit (lsb). Bit b (8n-1) is recorded first.

5.2

Names The names of entities, e.g. specific tracks, fields, areas, zones, etc. are given a capital initial.

General description of a disk The 120 mm and 80 mm optical disks that are the subject of this Ecma Standard consist of two substrates bonded together by an adhesive layer, so that the recording layers are on the inside. The centring of the disk is performed on the edge of the centre hole of the assembled disk on the side currently read. Clamping is performed in the Clamping Zone. The DVD Re-recordable Disk for Dual Layer (DVD-RW for DL) may be either double-sided or single-sided with respect to the number of recording layers. A double-sided disk has the recording layers on the inside of each substrate. A single-sided disk has one substrate with the recording layers on the inside and a dummy substrate without a recording layer. A recorded disk provides for the data to be read many times by an optical beam of a drive. Figure 1 shows schematically a double-sided (Type 2S) and a single-sided (Type 1S) disk. Type 1S consists of a substrate, two recording layers with a space layer between them, an adhesive layer, and a dummy substrate. Both recording layers can be accessed from one side only. The nominal capacity is 8,54 Gbytes for a 120 mm disk and 2,66 Gbytes for an 80 mm disk. Type 2S consists of two substrates, each having two recording layers with a space layer between them, and an adhesive layer. From one side of the disk only one pair of recording layers can be accessed. The nominal total capacity is 17,08 Gbytes for a 120 mm disk and 5,32 Gbytes for an 80 mm disk.

ID Error Detection Code When identifying all bytes of the array shown in Figure 28 as C i ,j for i = 0 to 11 and j = 0 to 171, the check bytes for ID Error Detection code (IED) are represented by C 0,j for j = 4 to 5. Their setting shall be obtained as follows. 5

17.3

RSV This field shall consist of 6 bytes. Their setting is application dependent, for instance a video application. If this setting is not specified by the application, the default setting shall be all ZEROs.

17.4

Error Detection Code This field shall contain four check bytes of Error Detection Code (EDC) computed over the preceding 2 060 bytes of the Data Frame. Considering the Data Frame as a single bit field starting with the most significant bit of the first byte of the ID field and ending with the least significant bit of the EDC field, then this msb will be b 16 511 and the lsb will be b 0. Each bit b i of the EDC shall be as follows for i = 31 to 0: 0

EDC(x) = ∑ bi xi = I(x) mod G(x) i=31

where: 32

I(x) = ∑ bi xi i=16 511

G(x) = x32 + x31 + x4 + 1.

Scrambled Frames The 2 048 Main Data bytes shall be scrambled by means of the circuit shown in Figure 31 which shall consist of a feedback bit shift register in which bits r 7 (msb) to r 0 (lsb) represent a scrambling byte at each 8-bit shift. At the beginning of the scrambling procedure of a Data Frame, positions r 14 to r 0 shall be pre-set to the value(s) specified in Table 3. The same pre-set value shall be used for 16 consecutive Data Frames. After 16 groups of 16 Data Frames, the sequence is repeated. The initial pre-set number is equal to the value represented by bits b 7 (msb) to bit b 4 (lsb) of the ID field of the Data Frame. Table 3 specifies the initial pre-set value of the shift register corresponding to the 16 initial pre-set numbers. Table 3 — Initial value of shift register Initial pre-set number

Figure 31 — Feedback shift register for generating scramble data

The part of the initial value of r 7 to r 0 is taken out as scrambling byte S0. After that, 8-bit shift is repeated 2 047 times and the following 2 047 bytes shall be taken from r7 to r 0 as scrambling bytes S1 to S2047. The Main Data bytes D k of the Data Frame become scrambled bytes D’ k where D’k = D k ⊕ Sk

for k = 0 to 2 047

⊕ stands for Exclusive OR.

ECC Block configuration An ECC Block is formed by arranging 16 consecutive Scrambled Frames in an array of 192 rows of 172 bytes each, see Figure 32. To each of the 172 columns, 16 bytes of Parity of Outer Code are added, then, to each of the resulting 208 rows, 10 byte of Parity of Inner Code are added. Thus a complete ECC Block comprises 208 rows of 182 bytes each. The bytes of this array are identified as Bi,j as follows, where i is the row number and j the column number. Bi,j for i = 0 to 191 and j = 0 to 171 are bytes from the Scrambled Frames Bi,j for i = 192 to 207 and j = 0 to 171 are bytes of the Parity of Outer Code Bi,j for i = 0 to 207 and j = 172 to 181 are bytes of the Parity of Inner Code

The PO and PI bytes shall be obtained as follows. In each of columns j = 0 to 171, the 16 PO bytes are defined by the remainder polynomial R j (x) to form the outer code RS (208,192,17). 207

Rj(x) =

∑ Bi,j x207-i = Ij(x) x16 mod GPO(x)

i=192

where: 191

Ij(x) =

∑ Bi,j x191-i i=0 15

GPO(x) = Π (x + αk ) k=0

In each of rows i = 0 to 207, the 10 PI bytes are defined by the remainder polynomial R i (x) to form the inner code RS (182,172,11). 181

Ri(x) =

∑ Bi,j x181-j = Ii(x) x10 mod GPI(x)

j=172

where: 171

Ii(x) =

∑ Bi,j x171-j

GPI(x) = Π (x + αk ) k=0

α is the primitive root of the primitive polynomial P(x) = x 8 + x 4 + x 3 + x 2 + 1.

Recording Frames Sixteen Recording Frames shall be obtained by interleaving one of the 16 PO rows at a time after every 12 rows of an ECC Block, see Figure 33. This is achieved by re-locating the bytes Bi,j of the ECC Block as Bm,n for m = i + int [i / 12] and n = j for i ≤ 191 m = 13 (i - 191) - 1 and n = j for i ≥ 192 where int [x] represents the largest integer not greater than x. Thus the 37 856 bytes of an ECC Block are re-arranged into 16 Recording Frames of 2 366 bytes. Each Recording Frame consists of an array of 13 rows of 182 bytes.

Modulation The 8-bit bytes of each Recording Frame shall be transformed into 16-bit Code Words with the run length limitation that between 2 ONEs there shall be at least 2 ZEROs and at most 10 ZEROs (RLL 2,10). Annex G specifies the conversion Tables to be applied. The Main Conversion Table and the Substitution Table specify a 16-bit Code Word for each 8-bit bytes with one of 4 States. For each 8-bit byte, the Tables indicate the corresponding Code Word, as well as the State for the next 8-bit byte to be encoded. The 16-bit Code Words shall be NRZI-converted into Channel bits before recording on the disk, see Figure 34. 16-bit Code Words

Physical Sectors The structure of a Physical Sector is shown in Figure 35. It shall consist of 13 rows, each comprising two Sync Frames. A Sync Frame shall consist of a SYNC Code from Table 4 and 1 456 Channel bits representing the first, respectively the second 91 8-bit bytes of a row of a Recording Frame. The first row of the Recording Frame is represented by the first row of the Physical Sector, the second by the second, and so on.

The Physical Sector is a sector after the modulation by 8/16 conversion which adds a SYNC Code to the head of every 91 bytes in the Recording Frame.

Suppress control of the d.c. component To ensure a reliable radial tracking and a reliable detection of the HF signals, the low frequency content of the stream of Channel bit patterns should be kept as low as possible. In order to achieve this, the Digital Sum Value (DSV, see 4.10) shall be kept as low as possible. At the beginning of the modulation, the DSV shall be set to 0. The different ways of diminishing the current value of the DSV are as follows. a) Choice of SYNC Codes between Primary or Secondary SYNC Codes. b) For the 8-bit bytes in the range 0 to 87, the Substitution Table offers an alternative 16-bit Code Word for all States. c) For the 8-bit bytes in the range 88 to 255, when the prescribed State is 1 or 4, then the 16-bit Code Word can be chosen either from State 1 or from State 4, so as to ensure that the RLL requirement is met. In order to use these possibilities, two data streams, Stream 1 and Stream 2, are generated for each Sync Frame. Stream 1 shall start with the Primary SYNC Code and Stream 2 with the Secondary - 47 -

SYNC Code of the same category of SYNC Codes. As both streams are modulated individually, they generate a different DSV because of the difference between the bit patterns of the Primary and Secondary SYNC Codes. In the cases b) and c), there are two possibilities to represent an 8-bit byte. The DSV of each stream is computed up to the 8-bit byte preceding the 8-bit byte for which there is this choice. The stream with the lowest ⎜DSV⎜ is selected and duplicated to the other stream. Then, one of the representations of the next 8-bit byte is entered into Stream 1 and the other into Stream 2. This operation is repeated each time case b) or c) occurs. Whilst case b) always occurs at the same pattern position in both streams, case c) may occur in one of the streams and not in the other because, for instance, the next State prescribed by the previous 8-bit byte can be 2 or 3 instead of 1 or 4. In that case the following 3-step procedure shall be applied. 1) Compare the ⎜DSV⎜s of both streams. 2) If the ⎜DSV⎜ of the stream in which case c) occurs is smaller than that of the other stream, then the stream in which case c) has occurred is chosen and duplicated to the other stream. One of the representations of the next 8-bit byte is entered into this stream and the other into the other stream. 3) If the ⎜DSV⎜ of the stream in which case c) has occurred is larger than that of the other stream, then case c) is ignored and the 8-bit byte is represented according to the prescribed State. In both cases b) and c), if the ⎜DSV⎜s are equal, the decision to choose Stream 1 or Stream 2 is implementation-defined. The procedure for case a) shall be as follows. At the end of a Sync Frame, whether or not case b) and or case c) have occurred, the DSV of the whole Sync Frame is computed and the stream with the lower ⎜DSV⎜ is selected. If this DSV is greater than + 63 or smaller than -64, then the SYNC Code at the beginning of the Sync Frame changed from Primary to Secondary or vice versa. If this yields a smaller ⎜DSV⎜, the change is permanent, if the ⎜DSV⎜ is not smaller, the original SYNC Code is retained. During the DSV computation, the actual values of the DSV may vary between -1 000 and +1 000, thus it is recommended that the count range for the DSV be at least from -1 024 to +1 023.

Linking scheme The linking scheme is specified for appending data in the Incremental recording mode. It consists of three types of linking methods named 2K-Link, 32K-Link and Lossless-Link.

24.1

Structure of linking The appended data shall be recorded from or to the Linking sector, which is the first Physical Sector of the ECC Block and it contains the linking point. On each linking operation, the data recording shall be terminated at the 16th byte in the first Sync Frame of the Linking sector and shall be started at the 15th to 17th byte in the first Sync Frame of Linking sector. When a disk is in the case of Figure 36 (b), Block SYNC Guard Area shall be located in the first ECC Block before linking and becomes a part of the Linking Loss Area after linking. The ECC Block address of Layer 0 shall be continuously decreased from the inside to the outside of a disk, however, the ECC Block address of Layer 1 shall be continuously decreased from the outside to the inside of a disk.

24.2

2K-Link and 32K-Link A Linking Loss Area shall be allocated in cases of 2K-Link and 32K-Link to prevent any degradation of the data reliability due to the influence of linking. It may contain padding sectors as shown in Figures 37 (2K-Link) and 38 (32K-Link) and shall have a minimum size of 2 048 bytes and 32 768 bytes respectively. All Main data in the Linking Loss Area shall be set to (00). - 48 -

The Data type bit (see 17.1) of the sector followed by a sector belonging to the Linking Loss Area shall be set to ONE, but the Data type bit of the Linking sector is always set to ZERO. See Figure 37 and 38. The last recorded sector in each RZone shall be recorded by using 2K-Link or 32KLink and its Data type bit shall be set to ONE.

24.3

Lossless-Link The linking without Linking Loss Area, as shown in Figure 39, is allowed and referred to as Lossless-Link. There is no sector which has the Data type bit of ONE in this linking scheme. ECC block address (X+1)

Section 5 — Format of the Information Zone 25

General description of the Information Zone The Information Zone extending over two layers shall be divided in four parts: the Lead-in Zone, the Data Zones, the Lead-out Zone and the Middle Zones. The Data Zones are intended for the recording of Main Data. The Lead-in Zone contains control information. The Lead-out Zone allows for a continuous smooth read-out. The Middle Zones facilitate layer jump at the end of the Data Zone on Layer 0 and allows for a continuous smooth read-out and read-in on each layer.

25.1

Layout of the Information Zone The Information Zone on Layer 0 shall be sub-divided as shown in Table 5. The values of the radii indicated are nominal values for the first Physical Sector and the last track of the last Physical Sector of a zone. The Information Zone on Layer 1 is also sub-divided according to the zone allocation on Layer 0 as shown in Table 6. Tracks are read from the outer side towards inner side of a disk on Layer 1.

Physical Sector numbering Physical sectors on the track shall not possess any gap and shall be placed continuously from the beginning of the Lead-in Zone to the end of the Middle Zone, as well as from the beginning of the Middle Zone to the end of the Lead-out Zone. The Physical sector numbers of Layer 0 shall continuously increase from the beginning of the Lead-in Zone to the end of the Middle Zone, however, the physical sector numbers of Layer 1 shall take the bit inverted value to that of Layer 0 and shall continuously increase from the beginning of the Middle Zone (outside) to the end of the Lead-out Zone (inside). The first sector number of the Data Zone on Layer 1 shall be the bit-inverted number of the last sector number in the Data Zone on Layer 0. The bit-inverted number shall be calculated so that the bit value of ONE becomes that of ZERO and vice versa. Sectors on each layer with bit-inverted sector numbers to each other are at almost the same distance from the center of the disk. The sector numbers shall be calculated by letting the sector number of the sector placed at the beginning of the Data Zone located after the Lead-in Zone be 196608 (030000). See Figure 40.

Section 6 — Format of the Unrecorded Zone 27

General description of the Unrecorded Zone A continuous spiral pre-groove forms the track of the Unrecorded Zone. The track extends from the inner part of the disk to the outer part of the disk on Layer 0 and from the outer part of the disk to the inner part of the disk on Layer 1 respectively. The track is wobbled at a specified frequency to control the drive functions. The precise address information for an unrecorded disk is embossed on the land between adjacent grooved regions. The Unrecorded Zone shall be divided into three parts: the R-Information Zone, the Initial Information Zone and the Outer Disk Testing Area. The R-Information Zone shall be divided into two parts: the Inner Disk Testing Area and the Recording Management Area. The Initial Information Zone of each layer shall be divided into three parts with Opposite Track Path as shown in Figure 47. Starting from the inner radius on Layer 0, these zones are the Lead-in Zone, the Data Recordable Zone, and the fixed Middle Zone. Starting from the outer radius on Layer 1, these zones are the fixed Middle Zone, the Data Recordable Zone, and the Lead-out Zone. The shifted Middle Zone can be added to inner side accompanying with unrecorded area. The allocation of the Lead-out Zone and the Middle Zone will be determined by finalization. These six zones are essential and identical in principle to the same zones on a dual layer type of DVD-Read-Only disk. The recording data shall be recorded in the pre-groove guided by the wobble and Pre-pit Information that is embossed in the land. The accurate start address before recording shall be determined by decoding the Pre-pit Information on the land.

27.1

Layout of the Unrecorded Zone The Unrecorded Zone of each layer shall be sub-divided as shown in Table 31 and 32 respectively. The ECC Block address (see clause 27.2) of the first block of each zone is shown in those tables. Table 31 — Layout of the Unrecorded Zone on Layer 0 ECC Block address of the first block of the Zone

Pre-pit Data format

28.1

General description The Pre-pit Data is embossed as a sequence of Pre-pits on the land. The Pre-pit Data sequence corresponds to 16 sectors of the same physical size as 1 ECC Block to be recorded in the groove. One set of Pre-pits shall be given by 3 bits (b2, b 1, b 0) every two SYNC Frames. The first set of Pre-pits in a Pre-pit physical sector is the Pre-pit SYNC Code. The first bit of the 3 bits is called the frame SYNC bit. In the Incremental recording mode, the frame SYNC bit shall be located at the special position of the recorded SYNC Code of the 16-bit Code Words in the groove. The assignment of these bits shall be as shown in Table 33. Table 33 — Assignment of Land Pre-pit b2

The assigned position of Pre-pits and the SYNC pattern of 16-bit Code words shall be as shown in Figures 48 and 49. The relation in phase between wobble and Land Pre-pit also shall be as specified in 14.5.3.

There are two cases of Pre-pit position in two SYNC Frames called Even position and Odd position. Normally the Pre-pit should be recorded at the Even position. In mastering, when there is already a Pre-pit on the neighbouring land, the position of the Pre-pits shall be shifted to the Odd position sequence. Such a case is described in Figure 50. The Pre-pits position can be shifted in a Pre-pit physical sector.

The Pre-pit data frame shall consist of 4 bits of relative address specified in 28.3.1 and 8 bits of user data. Pre-pit data shall be recorded in the user data area of the Pre-pit data frame. The Pre-pit data frame shall be as shown in Figure 51. The Pre-pit physical sector shall be a Pre-pit data frame after transforming 1 bit into 3 bits and adding Pre-pit SYNC Code. The Pre-pit physical sector shall be recorded on the land as part of the Land Pre-Pit recording. See Figure 52 and Table 33.

Pre-pit block structure A Pre-pit data block shall be constructed with 16 Pre-pit data frames. The Pre-pit data block shall have two data parts, part A and part B. Part A shall consist of 3 bytes of ECC Block address (see 28.3.2) and 3 bytes of parity A (see 28.3.3), and relative address 0000 to 0101 (see 28.3.1), thus Part A is constructed with 6 Pre-pit data frames. Part B shall consist of 1 byte of Field ID, 6 bytes of disk information and 3 bytes of parity B and relative address 0110 to 1111. Thus Part B is constructed with 10 Pre-pit data frames. The Pre-pit physical block shall be constructed with 16 Pre-pit physical sectors which are constructed by transforming each 1 bit of Pre-pit data block to 3 bits and adding the Pre-pit SYNC Code. This signal processing shall be as shown in Figure 53.

29.2

Structure of the Disk Testing Area The Inner Disk Testing Area shall be located from ECC Block address (FFE077) to (FFDE33) on Layer 0 and from (00240A) to (0021C6) on Layer 1. See Figure 65. The Outer Disk Testing Area shall be located from ECC Block address (FDCCC9) to (FDC887) on Layer 0 and from (0239B6) to (023574) on Layer 1. See Figure 66. When the shifted Middle Zone is applied, the start sector number of shifted Middle Zone shall be set in the RMD Field0. See 29.3.2.1.1 (Bytes 86 to 89) and 29.3.2.2.1 (Bytes 86 to 89). When the address X is set to the Last address of Data Recordable Zone on Layer 0 in the pre-pit data block Field ID1, the shifted Middle Zone shall be located inner than or equal to X+(AC1) on Layer 0 and X - (AC1) on Layer 1 respectively. When the address Y is the Last address of Data Recordable Zone according to adoption of the shifted Middle Zone, the shifted Middle Zone shall be located as shown in Table 36. When the shifted Middle Zone is applied, the outer diameter of Information Zone shall satisfy the requirement as described in 10.7. Therefore, if the diameter of the address Y is smaller than 69.2 mm, the shifted Middle Zone shall be located up to 70.0 mm. The shifted Middle area shall be located as shown in Table 36. - 86 -

Disk Testing Area on one layer shall not be overlapped by the Disk Testing Area on the other layer. Therefore Gap in radial direction shall be allocated between the Disk Testing Area on each layer, and the position of Gap shall be flexible according the usage of each Disk Testing Area. In each Disk Testing Area, the recording power calibration shall be performed by the following procedure. The minimum segment for a power calibration shall be one Pre-pit Physical sector and is referred to as a power calibration sector. The power calibration process shall be performed continuously from the start to the end of the power calibration sector. It is recommended that signal with enough readout amplitude should be recorded at the sector taking the largest address value in the used sectors on each power calibration process to find out the boundary with unused area easily. The signal should have a length of at least 4 consecutive Sync frames of power calibration sector and at least 0.5 of Modulation amplitude (I14/I14H) or equivalent. See Figure 13. This signal should be recorded at the sector taking the largest address value in the used sectors, and at least once in every 32 consecutive sectors. The IDTA shall consist of 581 ECC blocks (9 296 sectors) per each Layer. When Gap locates in the IDTA, the size of Gap and usable area for OPC in IDTA are 257 ECC blocks (4 112 sectors) and 324 ECC blocks (5 184 sectors) respectively. The ODTA shall consist of 1091 ECC blocks (17456 sectors) per each layer. When Gap locates in the ODTA, the size of Gap and usable area for OPC in ODTA are 676ECC blocks (10816 sectors) and 415 ECC Blocks (6640 sectors) respectively. The structure of the Disk Testing Area shall be as shown in Figure 65 and Figure 66. The power calibration of Layer 0 shall be performed from the outside to the inside of the disk, and the power calibration of Layer 1 shall be performed from the inside to the outside of the disk. 16 ECC blocks (256 power calibration sectors) in the most outer side of the IDTA on Layer 0 shall be reserved for the disk manufacturer. The IDTA for drive shall consist of 4928 power calibration sectors. 16 ECC blocks (256 power calibration sectors) in the most inner side of the ODTA on Layer 1 shall be reserved for the disk manufacturer. The ODTA for drive shall consist of 6 384 power calibration sectors. The power calibration process for disk manufacturer shall be user specific, but it is recommended that at least outer 8 ECC blocks in the IDTA on Layer 0 and inner 8ECC blocks in the ODTA on Layer 1 should be kept unrecorded state to make stable the recordings of the first RMD and the first Middle Zone, respectively.

Annex B (normative)

Measurement of birefringence

B.1 Principle of the measurement In order to measure the birefringence, circularly polarized light in a parallel beam is used. The phase retardation is measured by observing the ellipticity of the reflected light.

θ radial direction

Figure B.1 — Ellipse with ellipticity e = b/a and orientation θ

The orientation θ of the ellipse is determined by the orientation of the optical axis θ = γ - π/4

(I)

where γ is the angle between the optical axis and the radial direction. The ellipticity e = b/a is a function of the phase retardation δ ⎡1 ⎛ π ⎞⎤ e = tan ⎢ ⎜ − δ ⎟⎥ 2 2 ⎠⎦ ⎣ ⎝

(II)

When the phase retardation δ is known the birefringence BR can be expressed as a fraction of the wavelength BR =

λ δ nm 2π

(III)

Thus, by observing the elliptically polarized light reflected from the disk, the birefringence can be measured and the orientation of the optical axis can be assessed as well.

B.2 Measurements conditions The measurement of the birefringence specified above shall be made under the following conditions. Mode of measurement in reflection, double pass through the substrate Wavelength λ of the laser light

β Disk

Figure B.2 — Example of a device for the measurement of birefringence

Light from a laser source, collimated into a polarizer ( extinction ratio ≈ 10 - 5 ), is made circular by a λ/4 plate. The ellipticity of the reflected light is analyzed by a rotating analyzer and a photo detector. For every location on the disk, the minimum and the maximum values of the intensity are measured. The ellipticity can then be calculated as e 2 = Imin / Imax

(IV)

Combining equations II, III and IV yields BR =

I λ λ − arctan min 4 π Imax

This device can be easily calibrated as follows − Imin is set to 0 by measuring a polarizer or a λ/ 4 plate , − Imin = Imax when measuring a mirror Apart of the d.c. contribution of the front surface reflection, a.c. components may occur, due to the interference of the reflection(s) of the front surface with the reflection(s) from the recorded layer. These a.c. reflectance effects are significant only if the disk substrate has an extremely accurate flatness and if the light source has a high coherence.

Annex C (normative)

Measurement of the differential phase tracking error

C.1 Measuring method for the differential phase tracking error The reference circuit for the measurement of the tracking error shall be that shown in Figure C.1. Each output of the diagonal pairs of elements of the quadrant photo detector shall be digitized independently after equalization of the waveform defined by H(s) = (1 + 1,6 × 10 -7 iω) / (1 + 4,7 × 10 -8 iω) The gain of the comparators shall be sufficient to reach full saturation on the outputs, even with minimum signal amplitudes. Phases of the digitized pulse signal edges (signals B1 and B2) shall be compared to each other to produce a time-lead signal C 1 and a time-lag signal C 2. The phase comparator shall react to each individual edge with signal C 1 or C 2, depending on the sign of Δti . A tracking error signal shall be produced by smoothing the C 1, C 2 signals with low-pass filters and by subtracting by means of a unity gain differential amplifier. The low-pass filters shall be 1st order filters with a cut-off frequency of (-3 dB) 30 kHz. Special attention shall be given to the implementation of the circuit because very small time differences have to be measured, indeed 1 % of T equals only 0,38 ns. Careful averaging is needed. The average time difference between two signals from the diagonal pairs of elements of the quadrant detector shall be Δt = 1/N ∑Δti

where N is the number of edges both rising and falling.

C.2 Measurement of Δt /T without time interval analyzer The relative time difference Δt /T is represented by the amplitude of the tracking error signal provided that the amplitudes of the C 1 and C 2 signals and the frequency component of the read-out signals are normalized. The relation between the tracking error amplitude ΔTVE and the time difference is given by ΔTVE =

∑ Δti Vpc = ∑ Δti Vpc = Δt × Vpc T n NnT ∑ Ti

where Vpc is the amplitude of the C 1 and C 2 signals Ti is the actual length of the read-out signal in the range 3T to 14T nT is the weighted average value of the actual lengths N n T is the total averaging time Assuming that Vpc equals ≈ 5 V and that the measured value of n equals ≈ 5, then the above relation between the tracking error amplitude ΔTVE and the time difference Δt can be simplified to ΔTVE = Δt / T

The specification for the tracking gain can now be rewritten by using the tracking error amplitude as follows - 113 -

0,5 (Vpc/n) ≤ ΔTVE ≤ 1,1 (Vpc/n) at 0,1 μm radial offset.

C.3 Calibration of Δt /T As the gain of the phase comparator tends to vary, special attention shall be given to the calibration of the gain of the phase comparator. The following check and calibration method shall be applied for the measurement of the DPD tracking error signal. a) Checking the measurement circuit a.1) Measure the relation between the amplitude of the first comparator input (3T) and the amplitude of the tracking error signal. a.2) Check the current gain of the amplifier, using the saturation area (see Figure C.2). b) Determination of the calibration factor K b.1) Generate two sinusoidal signals A1 and A2 of frequency 2,616 MHz (corresponding to 5T) with phase difference, and feed them into two equalizer circuits. b.2) Measure the relation between Δt /T and ΔTVE / Vpc. ( ΔTVE / Vpc) K = ( Δt / T) / n K = (0,2 Δt /T) / ( ΔTVE / Vpc) for n = 5 The relation between Δt /T and ΔTVE / Vpc is linear (see Figure C.3). c) Compare the measured Δt /T with the calculated one c.1) Measure Δt /T using the method of C.1. c.2) Calculate Δt /T(real) as follows

Δt /T (real) = K × Δt /T (measured)

Now the arrangement is calibrated and the focused reflectivity is a linear function of the reflectivity of the recorded layer, independently from the reflectivity of the entrance surface.

D.2 Measuring method The measuring method comprises the following steps. a) Measure the reflective light power D s from the reference disk with calibrated reflectivity R s b) Measure I14H in the Information Zone of the disk (see 13.3) c) Calculate the reflectivity as follows I R14H = Rs × 14H Ds

X15(t) = msb and X0(t) = lsb

The Code Words leaving the States shall be chosen so that the concatenation of Code Words entering a State and those leaving that State satisfy the requirement that between two ONEs there shall be at least 2 and at most 10 ZEROs. As additional requirements:

− Code Words leaving State 2 shall have both bit x15 and bit x3 set to ZERO, and − in Code Words leaving State 3 bit x15 or bit x 3 or both shall be set to ONE. This means that the Code Word sets of States 2 and 3 are disjoint.

Figure G.2 — Determination of States

Note that when decoding the recorded data, knowledge about the encoder is required to be able to reconstitute the original main Data. B(t) = H -1 {X(t), S(t)} Because of the involved error propagation, such state-dependent decoding is to be avoided. In the case of this 8-to-16 modulation, the conversion Tables have been chosen in such a way that knowledge about the State is not required in most cases. As can be gathered from the Tables, in some cases, two 8-bit bytes, for instance the 8-bit bytes 5 and 6 in States 1 and 2 in Table G.1, generate the same 16-bit Code Words. The construction of the Tables allows to solve this apparent ambiguity. Indeed, if two identical Code Words leave a State, one of them goes to State 2 and the other to State 3. Because the setting of bits X15 and X3 is always different in these two States, any Code Word can be uniquely decoded by analysing the Code Word itself together with bits X 15 and X3 of the next Code Word: B(t) = H -1 { X(t), X15 (t+1), X3 (t+1) } In the Tables, the 8-bit bytes are identified by their decimal value.

Annex H (normative)

Optimum Power Control The laser power used for recording a disk is dependent on both the disk and the recorder that are being used, therefore this power shall be determined for the combination of each recorder and disk. Such a determination of the actual optimum recording power Po and erasing power Pe is called Optimum Power Control (OPC). To facilitate the OPC, a reference values for the recording power and erasing power are given for each layer individually. These values are encoded as special information in the extended PFI fields in Control Data Zone (see clause 28). These values are the OPC suggested code at the reference speed. The OPC shall be performed in an area on the disk that is specially reserved for this purpose: the Disk Testing Area (DTA) (see clause 29). The optimum recording power and the erasing power are the laser power at which jitter is minimized at the measuring conditions of the recorded disk specifications (see clause 13). Three examples of OPC procedure which make the determination of Po and Pe easier for practical device electronics is described below. Example 1: OPC procedure using β value for Layer 1 (Informative)

The asymmetry of the recorded 8/16 modulated data is different for different recording powers and erasing powers, therefore, the optimum recording power and erasing power for the specific combination of device and disk can be obtained by test recording 8/16 modulated data with different recording powers and erasing powers, and by measuring the resulting asymmetry in the HF signal. But directly using the definition of asymmetry is too complicated for the device electronics, therefore, a different parameter is defined as a representation of asymmetry. This parameter β is based on using the AC coupled HF signal before equalisation, and is defined as follows; β= (A1+A2) / (A1–A2) where (A1+A2) : the difference between the peak levels A 1 and A2 of the HF signal (A1–A2) : the peak-to-peak value of the HF signal See Figures H.1 to H.3. Zero asymmetry of the measured HF signal results in β = 0. β shall be measured with the PUH for recording as specified in 9.1.2, and asymmetry shall be measured with the PUH for reading as specified in 9.1.1 respectively. This means that for each design, a conversion shall be made from recorder read-out conditions to the conditions of the read-only pick-up.

Example 2: OPC procedure using γ value (Informative)

The example 2 described below may be effective to determine Po and Pe easier for practical recorder drive electronics. To obtain the accurate OPC results, the modulation versus recording power curve m(Pw) shall be determined in a power range with sufficient variation of the modulation as a function of the power with the normalized slope γ. The OPC procedure determines the value Ptarget of the power for γ = γ target for the supposed actual combination between disk and recorder. To facilitate the OPC procedure, the values ε and Pind are obtained from the special information in the extended PFI fields in Control Data Zone. These values can be used as starting values in test recordings by each drive for the determination of the actual optimum values Po and Pe. The relevance of the parameters for determining Po and Pe is shown in the following formulas and Figure H.4. 

Example 3: OPC procedure using Ke value for Layer 0 (Informative)

The example described below is effective to determine Po and Pe for Layer 0. This procedure (Ke method) consists of two steps. Step-1 (Pe-OPC procedure):

Step-1 is the procedure to determine Pe value using Ke value. To obtain the accurate OPC results, the pre-recorded base marks are erased with various DC erasing powers. Pe is obtained by using the Pe-target value and Ke value. Step1-1 (Pre-recording):

The 8/16 modulated marks are pre-recorded by the recoding power Pind and erasing power (= ε × Pind). Pind and ε value are stored in the OPC suggested code field.

Step1-2 (DC erasing):

Those marks are erased with various DC erasing power around ε × Pind/Ke. By measurements of the residual modulation m1 at each DC erasing power, the normalized slope parameter γ e is derived:

γ e(PDC ) = (dm1/dPDC ) × (PDC /m1), where m1 = m1(PDC ) Step1-3 (Pe-determination): Pe-target is determined as the DC erasing power at the minimum γ e ( γ e-min). Pe is obtained by: Pe = Ke × Pe-target The relevance of the parameters for determining Pe is shown in the following formulas and Figure H.5. m1 = I14/I14H:

Step-2 (Po determination):

Step-2 is the procedure to determine Po value using ε value. For accurate Po-OPC procedure, the test marks are recorded with various recording power around Recording power (Pind) stored in the OPC suggested code field, and the erasing power Pe obtained by Step-1. Po value is calculated by using ε value in the OPC suggested code field, and erasing power Pe obtained by Step-1. Po is obtained by: Po = Pe/ε where; ε
