Scope
This International Standard defines the characteristics of 90 mm Optical Disk Cartridges (ODC) with a
capacity of 2,3 GB per Cartridge. The Standard specifies only Type R/W for 2 048–byte 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 using the thermo-magnetic and magneto-optical effects. It is also referred to as "fully rewritable". This
International 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 interchange
ability between data processing systems;
the 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-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 from
the disk.
This International Standard provides for interchange between optical disk drives. Together with a standard for
volume and file structure, it provides for full data interchange between data processing systems.
