The Committee made major contributions to ISO
4、IIEC JTCllSC23 for the development of standards for 90 mm. 120 mm. 130 mm, 300 mm and 356 mm ODCs. ECMA produced camera-ready copies for most International ODC Standards. In addition, ECMA published the following OM3 Standards: ECMA-130 (1988) Data Interchange on Read-only 120 mm Optical Data Disks

ECMA-183, ECMA- 184 and ECMA-195 are JXMA Standards for 130 mm ODCs of different capacities, based on the optical
9、 disk carfridge specified in ISOIIEC 10089. Whilst the latter specifies a fully-rewritable disk, these ECMA Standards specify several related implementations depending on the application considered. Two or more Types are defined including fully- rewritable (Type WW), partially pre-recorded and parti
10、ally rewnkable (Type P-ROM), fully pre-recorded (Type O-ROM) disks or cartridges, and those with write once read multiple functionality (Type WO). A similar trend, towards more Types and increasing capacities, is followed by 90 mm ODCs based on the optical disk cartridge specified in ECMA-154 (ISOii
11、EC 1o090). The present ECMA Standard is a standard of the 90 mm ODC series. It specifies three Types providing a capacity of 230 Megabytes per cartridge.

45、a capacity of 230 Mbytes per Cartridge. The Standard specifies three related, but different implementations of such cartridges, viz. Type R/W Provides for data to be written, read and erased many times over the whole recording surface of the disk using the thermo-magnetic and magneto-opticai effects
46、. Type P-ROM Provides for a part of the disk surface to be embossed by stamping or other means. This part of the disk is read without recourse to the magneto-opticai effect. All parts which are not embossed provide for data to meet the requirements of Type RMr. means. This type of disk is read witho
47、ut recourse to the magneto-optical effect. Type O-ROM Provides for the whole of the disk surface to be embossed and reproduced by stamping or other Type RW, Type P-ROM and Type O-ROM are also referred to as “fully rewntable“. “partially embossed“ and “fully embossed“, respectively. This ECMA Standar
48、d specifies - the conditions for conformance testing and the Reference Drive; - the environments in which the cartridges are to be operated and stored; - the mechanical and physical characteristics of the cartridge, so as to provide mechanical interchangeability between data processing systems; - th
49、e format of the information on the disk, both embossed and user-written; including the physical disposition of the tracks and sectors, the error correction codes, and the modulation method used; - the characteristics of the embossed information on the disk; - the magneto-opticai characteristics of the disk, enabling processing systems to write data onto the disk; - the minimum 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. To
