ISO/IEC 22533:2005

Information technology — Data interchange on 90 mm optical disk cartridges — Capacity: 2,3 Gbytes per cartridge

ISO/IEC 22533:2005 defines the characteristics of 90 mm Optical Disk Cartridges (ODC) with a capacity of 2,3 GB per cartridge. It specifies only Type R/W for 2 048-byte sectors of such cartridge. Type R/W provides for data to be written, read and erased many times over the entire recording surface of the disk using the thermo-magnetic and magneto-optical effects. It is also referred to as "fully rewritable". ISO/IEC 22533:2005 provides for 2 048-byte sectors only. All sectors on a disk are of the same size. ISO/IEC 22533:2005 specifies: the conditions for conformance testing and the Reference Drive; the environments in which the cartridges are to be operated and stored; the mechanical and physical characteristics of the cartridge, so as to provide mechanical interchange ability 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. ISO/IEC 22533:2005 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.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 22533 was prepared by Ecma (as ECMA-353) and was adopted, under a special fast-track
procedure, by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 23,
Digital storage media for information interchange, in parallel with its approval by national bodies of ISO and
IEC.

Information technology — Data interchange on 90 mm optical
disk cartridges — Capacity: 2,3 Gbytes per cartridge
Section 1 - General
1 Scope
This International Standard defines the characteristics of 90 mm Optical Disk Cartridges (ODC) with a
capacity of 2,3 GB per Cartridge. The Standard specifies only Type R/W for 2 048–byte sectors of such
cartridge.
Type R/W provides for data to be written, read and erased many times over the entire recording surface of the
disk using the thermo-magnetic and magneto-optical effects. It is also referred to as "fully rewritable". This
International Standard provides for 2 048-byte sectors only. All sectors on a disk are of 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 and physical characteristics of the cartridge, so as to provide mechanical interchange
ability 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.
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.
2 Conformance
2.1 Optical disk Cartridge (ODC)
A claim of conformance with this International Standard shall specify the Type of the ODC. It shall be in
conformance if it meets all mandatory requirements specified herein for that Type.
2.2 Generating system
A claim of conformance with this International Standard shall specify which Type is supported. A system
generating an ODC for interchange shall be in conformance with this International Standard if it meets the
mandatory requirements of this International Standard for the Type specified.

ISO/IEC 22533:2005(E)
2.3 Receiving system
A claim of conformance with this International Standard shall specify which Type is supported. A system
receiving an ODC for interchange shall be in conformance with this International Standard if it is able to
process any recording made on the cartridge in accordance with 2.1 on the Type specified.
2.4 Compatibility statement
A claim of conformance with this International Standard shall include a statement listing any other
International Standard supported by the system for which conformance is claimed. This statement shall
specify the number of the Standard(s), the ODC type(s) supported (where appropriate) and whether support
includes reading or both reading and writing.
