40、hnical 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 a
41、ctivity. 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 co
42、mmittee ISO/IECJTC1. 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 least75%of the national bodies casting a vote. International Standard ISO/IEC13481 was prepared b
43、y the European Computer Manufacturers Association (as Standard ECMA-183) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC1, Information technology, in parallel with its approval by national bodies of ISO andIEC.

47、ODC) with a capacity of1Gbyte per cartridge. This International Standard specifies two related but different implementations of such cartridges, viz. 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
48、and magneto-optical effects. Type WO Provides write once, read multiple functionality on the whole of both disk surfaces using the thermo-magnetic and magneto-optical effects.ISO/IEC13481:1993(E) 2 BSI 01-2000 Section 1. General 1 Scope This International Standard specifies the characteristics of130
49、mm optical disk cartridges (ODCs) with a capacity of1Gigabyte per cartridge. It specifies two related, but different implementations of such cartridges: 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
