Information technology. Data interchange on 130 mm optical disk cartridges. Capacity: 1 gigabyte per cartridge
This International Standard specifies the characteristics of 130 mm optical disk cartridges (ODCs) with a capacity of
1 Gigabyte per cartridge. It specifies two related, but different implementations of such cartridges:
| Type R/W | Provides for data to be written, read and erased many times over the whole of both recording surfaces of the disk using the thermo-magnetic and magneto-optical effects. |
| Type WO | Provides write once, read multiple functionality on both disk surfaces using the thermo-magnetic and magnetooptical effects. |
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 case and 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, 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.
It also 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. Interchange involves the ability to write, read and erase data without introducing any error.
