28、 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 te
29、chnical 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.
30、 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 fo

35、 The standards recognize the existence of different methods for recording and reading information on optical memory cards, the characteristics of which are specific to the recording method employed. In general, these different recording methods will not be compatible with each other. Therefore, the
36、standards are structured to accommodate the inclusion of existing and future recording methods in a consistent manner. This part of ISO/IEC 11695 is specific to optical memory cards using the holographic recording method. Characteristics which apply to other specific recording methods shall be found
37、 in separate standards documents. This part of ISO/IEC 11695 defines the optical properties and characteristics and the extent of compliance with, addition to, and/or deviation from the relevant base document, ISO/IEC 11693. The International Organization for Standardization (ISO) and International
38、Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this document may involve the use of patents. The ISO and IEC take no position concerning the evidence, validity and scope of these patent rights. The holders of these patent rights have assured the
39、ISO and IEC that they are willing to negotiate licenses under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the Statements of the holders of these patent rights are registered with the ISO and IEC. Information may be obtained from: Baye
