This International Standard defines the characteristics of 90 mm Optical Disk Cartridges (ODC) with acapacity of 2,3 GB per Cartridge. The Standard specifies only Type R/W for 2 048–byte sectors of suchcartridge.Type R/W provides for data to be written, read and erased many times over the entire recording surface of thedisk using the thermo-magnetic and magneto-optical effects. It is also referred to as "fully rewritable". ThisInternational Standard provides for 2 048-byte sectors only. All sectors on a disk are of the same size.This International Standard 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;? the format of the information on the disk, both embossed and user-written; including the physicaldisposition 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-written data on the disk, enabling data processing systems to read data fromthe disk.This International Standard provides for interchange between optical disk drives. Together with a standard forvolume and file structure, it provides for full data interchange between data processing systems.
