Brief History

3、 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 toward the development of International Standards for 80 mm, 90 mm, 120 mm, 130 mm, 300 mm

4、, 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 the fast-track procedure as International Standards. ECMA has published the following 130 mm ECMA Standards for ODCs: ECMA-153 (1991) Information Inte

37、hanical, physical, and optical characteristics of a 130 mm optical disk cartridge (ODC) that employs thermo-magnetic and magneto-optical effects to enable data interchange between such disks. This ECMA Standard specifies two Types, viz. Type R/W provides for data to be written, read and erased many

38、time over the recording surface(s) of the disk. Type WO provides for data once written to be read a multiplicity of times. Data shall not be erased nor amended. Multisession (incremental write operations) recording may be performed on type WO disks. The disk shall be of the same Type if recorded on

39、both sides, A and B. Each side shall have a nominal capacity of 4,58 Gbytes, irrespective of the Type. The format specifies two sector sizes and allows for emulation of two further sizes. This ECMA Standard specifies the conditions for conformance testing and the Reference Drive; the environments in

40、 which the cartridges are to be operated and stored; the mechanical, physical and dimensional characteristics of the cartridge so as to provide mechanical interchangeability between data processing systems; the format of the information on the disk, both embossed and user-written, including the phys

41、ical disposition of the tracks and sectors, the error correction codes, the modulation methods used; the characteristics of the embossed information on the disk; the thermo-magnetic and magneto-optical characteristics of the disk, enabling processing systems to write data onto the disk; the minimum

42、quality of user-written data on the disk, enabling data processing systems to read data from the disk. This ECMA Standard provides for interchange between optical disk drives. Together with a standard for volume and file structure it provides for full data interchange between data processing systems
