9 0 ISOAEC lso/lecl3614:1995(e) 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 patt in the work. In the field of information technology, ISO and IEC have established a joint technical committee, lso/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 lso/iec was prepared by Joint Technical Committee lso/iec JTC 1, Information technology, Subcommittee SC 23, Optical disk caflridges for informa tion interchange. Annexes A to G and J form an integral patt of this Internationa to M are for information only. Standard. Annexes H and K

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 car-tridge 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 Standard and to read any such Optical disk cattridge 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 the Standard. 3 Normative references The following Standards contain provisions, which in reference with this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All Standards are subject to revision, and Parties to agreements based on this International Standard are encouraged to
