34、he characteristics of 90 mm Optical Disk Cartridges (ODC) with a capacity of 2,3 Gbytes per Cartridge. The Standard specifies only Type R/W for 2 048byte sectors of such cartridge. Type R/W provides for data to be written, read and erased many times over the entire recording surface of the disk usin
35、g the thermo-magnetic and magneto-optical effects. It is also referred to as “fully rewritable“. This Ecma Standard provides for 2 048-byte sectors only. All sectors on a disk are of the same size. This Ecma Standard specifies the conditions for conformance testing and the Reference Drive; the envir
36、onments in which the cartridges are to be operated and stored; the mechanical and physical characteristics of the cartridge, so as to provide mechanical interchange ability between data processing systems; the format of the information on the disk, both embossed and user-written; including the physi
37、cal 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-optical characteristics of the disk, enabling processing systems to write data onto the disk; the minimum quality of user-wr
