This International Standard specifies the characteristics of a series of related 130 mm optical disk cartridges (ODCs) by using a number of Type designations. A disk has two sides, called Side A and Side B. Each side can have a nominal capacity of 2,6 Gbytes. Type R/W provides for data to be written, read and erased many times over the recording surface of the corresponding disk side, using the thermo-magnetic and magneto-optical effects. Type P-ROM provides for a part of the disk surface to be pre-recorded and reproduced by stamping or other means. This part of the disk is read without recourse to the magneto-optical effect. All parts which are not pre-recorded provide for data to meet the requirements of Type R/W. Type O-ROM provides for the whole of the disk surface to be pre-recorded and reproduced by stamping or other means. The corresponding disk sides are read without recourse to the magneto-optical effect. Type DOW provides for data to be written and read many times over the recording surface of the corresponding disk side, using the direct overwrite thermomagnetic and magneto-optical effects requiring a single external magnetic field. Type P-DOW provides for a part of the disk surface to be pre-recorded and reproduced by stamping or other means. This part of the disk is read without recourse to the magneto-optical effect. All parts which are not pre-recorded provide for data to meet the requirements of Type DOW. Type WO provides write once, read multiple functionality using the thermo-magnetic and magneto-optical effects. Type WO-DOW provides write once, read multiple functionality using the direct overwrite thermo-magnetic and magneto-optical effects. In addition, for each Type, this International Standard provides for cartridges containing a disk with a sector size of 512 bytes, cartridges containing a disk with a sector size of 1 024 bytes and cartridges containing a disk with a sector size of 2 048 bytes. All sectors of a disk are the same size. This International Standard specifies - the conditions for conformance testing and the Reference Drive; - the environments in which the cartridges are to be operated and stored; - the mechanical, physical and dimensional characteristics of the cartridge, so as to provide mechanical interchangeability between 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, the modulation methods 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.
