3、sk Cartridges (ODC). Since its 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 als
4、o been adopted by ISO/IEC under the fast-track procedure as International Standards. In February 2002 a group of Companies proposed to TC31 to develop a standard for 120 mm rewritable optical disks using Phase Change recording technology and based on the DVD - Read-Only standard (ECMA-267) and the +
5、RW format (ECMA-274). TC31 adopted this project and started the work that has resulted in ECMA-337. In February 2005 a proposal was made to TC31 to develop a new Ecma Standard that supports high-speed recording of 120 mm and 80 mm rewritable disks based on the same technology as ECMA-337. This Ecma
6、Standard specifies two Types of rewritable optical disks, one (Type S) making use of recording on only a single side of the disk and yielding a nominal capacity of 4,7 or 1,46 Gbytes per disk and the other (Type D) making use of recording on both sides of the disk and yielding a nominal capacity of
7、9,4 or 2,92 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 requirements for information interchange between systems. This Ecma Standard has been adopted by the General As

30、uture Specifications 131 - 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 4,7 Gbytes and 9,4 Gbytes. It specifies the quality of the recorded and unrecorded signals, the
31、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 HS (High Speed). This Ecma Standard also specifies 80 mm disks w
32、ith capacities of 1,46 Gbytes and 2,92 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 but different
33、 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 format of th
34、e 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 provides for th
35、e 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 implemented.
