3、0015214 312 Brief history Technical Committee ECMA TC31 for Optical Disk Cartridges (OK) was set up in 1984. The Committee made major contributions to ISO/IEC/JTCl/SC23 for the development of 130 mm WORM Optical Disk Cartridges (ISO/IEC 9171) and of 130 mm Rewritable Optical Disk Cartridges using M.

4、O. (iSO/IEC 10089). ECMA produced the camera-redy copies for these International Standarb. In addition ECMA published the following Standards: ECMA-130 (1988) ECMA-153 (1991) ECMA-154 (1991) ECMA- 183 (1992) The first three of these ECMA Standards have been adopted unter the fast-track procedure of

5、ISO/EC JTC1 as International Standards ISOm 10149, ISO/IEC 11560 and ISO/IEC 1OO90, respectively. Standard ECMA-183 and the present ECMA Standard have also been contributed to ISO/IEC for adoption under the fast- track procedure as International Standards. They are the first of a series of ECMA Stan

6、dards for ODCs of different capacities, based on the optical disk cartridge specified in ISO/IEC 10089. Whilst the latter specifies a fully re-writable disk, these ECMA Standards Specis. severai related implementations depending on the application considered. Two or more Types are defined, including

This ECMA Standard specifies the characteristics of 130 mm Optical Disk Cartridges (ODC) with a capacity of 1,3 Gbytes per cartridge. Th

33、e Standard specifies four related, but different implementations of such cartridges, viz. Type Rfw Provides for data to be written, read, and erased many times over the whole of both recording surfaces of the disk using the thermo-magnetic and magneto-opticai effects. Type P-ROM Provides for a part

34、of both disk surfaces to be pre-recorded and reproduced by stamping or other means. This part of the disk is read without recourse to the magneto-optical effect. All parts which are not pre-recorded, provide for data to meet the requirements of Type R/W. Provides for the whole of both disk surfaces

35、to be pre-recorded and reproduced by stamping or other means. This type of disk is red without recourse to the magneto-optical effect.
