BS ISO/IEC 13549:1993

This standard BS ISO/IEC 13549:1993 Information technology. Data interchange on 130 mm optical disk cartridges. Capacity: 1,3 gigabytes per cartridge is classified in these ICS categories:

• 35.220.30 Optical storage devices

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.
