Specifies the characteristics of 130 mm Optical Disk Cartridges (ODC) with a capacity of 1,3 Gigabytes per cartridge. Coverage includes definitions, conformance, logical track, interleaving, Kerr rotation, physical track group, read power, recording layer, optical system, read channels, temperature shock, rotation of the disk, and flammability. Also gives detailed annexes.

This International Standard specifies

• the conditions for conformance testing;

• the environments in which the cartridges are to be operated and stored;

• the mechanical, physical and dimensional characteristics of the case and of the cartridges, so as to provide mechanical interchangeability between the 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.
