scope:

This International Standard specifies the characteristics of 356 mm optical disk cartridges of the type providing for information to be written once and read many times.

IS0 10885 specifies

- definitions of essential concepts,

- the environment in which the characteristics shall be tested,

- the environments in which the cartridge shall be operated and stored,

- the mechanical, physical and dimensional characteristics of the case and of the optical disk,

- the optical characteristics and the recording characteristics for recording the information once and for reading it many times, so as to provide physical interchangeability between data processing systems.

- the format for the physical disposition of the tracks and sectors, the error correction codes, the modulation methods used for recording and the quality of the recorded signals.

Together with a standard for volume and file structure, lSO/lEC 10885 provides for full data interchange between data processing systems.
