2、d 80 mm Optical Disk using +RW DL Format Capacity: 8,55 and 2,66 Gbytes per Side (Recording speed 2,4X) Standard ECMA-374 2ndEdition / June 2008 . Introduction Ecma Technical Committee TC31 was established in 1984 for the standardization of Optical Disks and Optical Disk Cartridges (ODC). Since its

3、establishment, the Committee has made major contributions to ISO/IEC toward the development of International Standards for 80 mm, 90 mm, 120 mm, 300 mm, and 356 mm media. Numerous standards have been developed by TC31 and published by Ecma, almost all of which have also been adopted by ISO/IEC under

4、 the fast-track procedure as International Standards. In June 2006 a group of Companies proposed to TC31 to develop a standard for 120 mm dual layer rewritable optical disks using Phase Change recording technology and based on the DVD - Read-Only standard (ECMA-267) and the +RW format (ECMA-337 and

5、ECMA-371). TC31 adopted this project and started the work that has resulted in this Standard. This Ecma Standard specifies two Types of rewritable optical disks, one (Type S9) making use of recording on only a single side of the disk and yielding a nominal capacity of 8,55 or 2,66 Gbytes per disk an

6、d the other (Type D18) making use of recording on both sides of the disk and yielding a nominal capacity of 17,1 or 5,32 Gbytes per disk. This Ecma Standard, taken together with a standard for volume and file structure, such as for instance developed in Ecma Technical Committee TC15, provides the re

7、quirements for information interchange between systems. This Ecma Standard has been adopted by the General Assembly of June 2008.

31、nted in Existing and Future Specifications 141 - vii - - viii - Section 1 General 1 Scope This Ecma Standard specifies the mechanical, physical and optical characteristics of 120 mm rewritable optical disks with capacities of 8,55 Gbytes and 17,1 Gbytes. It specifies the quality of the recorded and

32、unrecorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written, read and overwritten many times using the phase change method. These disks are identified as +RW DL. This Ecma Standard also specifies 80

33、 mm disks with capacities of 2,66 Gbytes and 5,32 Gbytes. These disks shall have the same characteristics as the 120 mm disks, except for some parameters related to the smaller dimensions. All parameters unique for the 80 mm disks are specified in Annex A. This Ecma Standard specifies two related bu

34、t different Types of this disk (see clause 7), the conditions for conformance, the environments in which the disk is to be tested, operated and stored, the mechanical, physical and dimensional characteristics of the disk, so as to provide mechanical interchange between data processing systems, the f

35、ormat of the information on the disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method, the characteristics of the signals recorded on the disk, thus enabling data processing systems to read the data from the disk. This Ecma Standard prov

36、ides for the interchange of disks between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems. 2 Conformance 2.1 Optical Disk A claim of conformance with this Ecma Standard shall specify the Type implement
