9 OISO/IEC ISO/IEC 13403: 1995(E) Foreword IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 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. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. 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. International Standard ISO/IEC was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 23, Optical disk cartridges for information interchange. Annexes A to G and J form an integral part of this International Standard. Annexes H and K to N are for information only. ix

10 INTERNATIONAL STANDAFW OISO/IEC ISO/IEC 13403:1995(E) Information technology - Information interchange on 300 mm optical disk cartridges of the write once, read multiple (WORM) type using the CCS method 1 Scope Section 1 : General This International Standard specifies the characteristics of 300 mm optical disk of the WORM type providing for embossed information and for data to be written once and read multiple times. It specifies - the conditions for conformance testing and the reference drive; - the mechanical and physical 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; - the characteristics of the embossed information on the disk; - the 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 syskms to read data from the. disk. Together with the standard for Volume and File Structure, this International Standard provides for full data interchange between data processing systems. Interchange involves the ability to write and read data without introducing any error. 2 Conformance A 300 mm optical disk cartridge is in conformance with this International Standard if it meets all mandatory requirements specified herein. A drive claiming conformance with this International Standard shall be able, in the operating environment, to write on any optical disk cartridge which is in conformance with this International Standard and to read any such optical disk cartridge which has been written with any drive in conformance with this International Standard. A drive shall not claim conformance if it cannot accept the full range of media conforming to this International Standard. 3 Normative references The following standards contain provisions which,through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subjected to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility 1
