Scope: This standard specifies the characteristics of a 130 mm optical disc cartridge (ODC) with a capacity of 1 Gbyte. This standard defines two related but distinct types of optical disc cartridges: R/W type uses thermomagnetic and magneto-optical effects on the entire recording surface of the disc to write once, read and erase data multiple times. The W/O type uses thermomagnetic effect and magneto-optical effect on the entire surface of the disk to write once and read data multiple times. This standard specifies the following: --conditions for performance testing and reference drives; --operating and storage environments for disc cartridges; - the mechanical interchangeability of the disc; - the format of information embossed on the disc or written by the user, including the physical location of tracks and sectors, error correction codes and modulation methods; - the characteristics of the information embossed on the disc; - the magnetic properties of the disc optical characteristics, so that the data processing system can read data from the disc; -- the minimum quality of user-written data on the disc, so that the data processing system can read data from the disc; this standard provides exchange. This standard, together with a standard on volumes and file structures, provides for full data exchange between data processing systems. Swapping involves the ability to write, read, and erase without causing any errors.
