2、 (8,54 Gbytes per side) and 80 mm (2,66 Gbytes per side) DVD Re-recordable Disk for Dual Layer (DVD-RW for DL) Standard ECMA-384 1stEdition / December 2008 . Introduction Ecma Technical Committee TC31 was established in 1984 for the standardization of Optical Disks and Optical Disk Cartridges (ODC).
3、 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-
4、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) ISO/IEC 16448 120 mm DVD-Read-Only Disk, 3rdedition ECM

8、 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 d
9、isk 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 be

ECMA-94 Latin Alphabet No.1 ECMA-287 Safety of electronic equipment 4 Definitions For the purpose of this Ecma Standard the fo
44、llowing definitions apply. 4.1 Basic recording speed A recording speed at which a disk is under an obligation to be recorded. A Basic recording speed is mandatory recording speed for each Class. 4.2 Block SYNC Guard Area The recorded area in the first ECC block of the contiguous area of which record
45、ing is started from the unrecorded area by using 32K-Link. 4.3 Channel bit The elements by which, after modulation, the binary values ZERO and ONE are represented on the disk by marks. 4.4 Clamping Zone The annular part of the disk within which a clamping force is applied by a clamping device. 4.5 C
46、lass Integer number, including 0, that indicates Basic recording speed supported by a disk. A group of recording speeds in a disk must contain at least one Basic recording speed which is mandatory for recording device and disk. 4.6 Data Zone The zone between the Lead-in Zone and the Middle Zone on L
47、ayer 0 and the zone between the Middle Zone and the Lead-out Zone on Layer 1, in which user data is recorded. 4.7 Data Recordable Zone The zone that is available to record user data. 4.8 Digital Sum Value (DSV) The arithmetic sum obtained from a bit stream by allocating the decimal value 1 to bits s
48、et to ONE and the decimal value 1 to bits set to Zero. 4.9 Disk Reference Plane A plane defined by the perfectly flat annular surface of an ideal spindle onto which the Clamping Zone of the disk is clamped, and which is normal to the axis of rotation. 4.10 Disk Testing Area (DTA) The area used for O
49、ptimum 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. - 3 - 4.11 ECC Block address The absolute physical address used to define
