3、chnical Committee ECMA TC31 for Optical Disk Cartridges (ODC) was set up in 1984. The committee made majorcontributions to ISO/IEC JTC1/SC23 for the development of 130 mm WORM Optical Disk Cartridges (ISO/IEC 9171) and of130 mm Rewritable Optical Disk Cartridges using M.O. (ISO/IEC 10089). ECMA prod

In addition ECMA published the following Standards:ECMA-130 (1988) Data Interchange on Read-only 120 mm Optical Data Disks (CD-ROM)ECMA-153 (1994) Information Interchange on 130 mm Optical Disk Cartridges of the Write Once,Read Multiple Type

7、1, ISO/IEC 13549 and ISO/IEC 13963, respectively.Standards ECMA-183 and ECMA-184 are the first of a series of ECMA Standards for ODCs of different capacities, based onthe optical disk cartridge specified in ISO/IEC 10089. Whilst the latter specifies a fully re-writable disk, these ECMAStandards spec

Two or more Types are defined,including fully re-writable, partially pre-recorded and partially re-writable, fully pre-recorded disks or cartridges and those withwrite once, read multiple functionality.The present standard

9、is a further ECMA Standard of this series. It specifies nine Types providing a capacity of 2 Gbytes percartridge. It is identical to International Standard ISO/IEC 13842.Adopted as 2nd Edition of Standard ECMA-195 by the ECMA General Assembly in June 1995.- i -Table of contentsSection 1: General 11

38、e designations.The two sides of the disk, called Side A and Side B, with each a nominal storage capacity of 1 Gigabyte are givenspecific Type designations. Thus, Side A and Side B may be different types.Types R/W, R/W-R provide for data to be written, read and erased many times over the whole of bot

39、hrecording surfaces of the corresponding disk side, using the thermo-magnetic andmagneto-optical effects.Types P-ROM, P-ROM-R provide for part of both disk surfaces to be pre-recorded and reproduced by stampingor other means. This part of the disk is read without recourse to the magnetico-optical ef

40、fect. All parts which are not pre-recorded provide for data to meet therequirements of Types R/W and R/W-R, respectively.Types O-ROM, O-ROM-R provide for the whole of both disk surfaces to be pre-recorded and reproduced bystamping or other means. The disk sides are read without recourse to the magne

41、to-optical effects.Types WO, WO-R provide write-once, read-multiple functionality using the thermo-magnetic and themagneto-optical effects.Type B indicates that the cartridge side shall not be used. This Type designation may be usedfor Side B only.The suffix - R, which may be used for Side B only, i

42、ndicates that the tracks of Side B spiral in the opposite direction tothose on Side A. Such ODCs facilitate simultaneous access to both sides of the disk by a dual optical system.The 20 combinations of Types allowed by this ECMA Standard for the two sides of disks are specified in table 2 in10.5.8.I

43、n addition, for each Type, this ECMA Standard provides for 512-byte and 1 024-byte sector sizes. All sectors of anODC are the same size.This ECMA Standard specifies the conditions for conformance testing and the Reference Drive; the environments in which the cartridges are to be operated and stored;

44、 the mechanical, physical and dimensional characteristics of the cartridge, so as to provide mechanicalinterchangeability between data processing systems; the format of the information on the disk, both embossed and user-written, including the physical disposition of thetracks and sectors, the error

45、 correction codes, the modulation methods used; the characteristics of the embossed information on the disk; the magneto-optical 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 system

46、s to read data from the disk.This ECMA Standard provides for interchange between optical disk drives. Together with a Standard for volume andfile structure it provides for full data interchange between data processing systems.2 Conformance2.1 Optical Disk Cartridge (ODC)An ODC claiming conformance w
