This standard specifies the characteristics of 130-mm optical disk cartridges (ODC) of the Write Once Multiple (WORM) type, which provides for the disk to be intialized once, and the information to be written once only and read many times using the magneto-optical effect.This standard 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 magneto-optical characteristics and the recording characteristics for initializing the disk once, for recording the information once, 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 method used for recording, and the quality of the recorded signals.
