10、technical Commission)form the specialized system for worldwide standardization. National bodies that are members of ISO or IECparticipate in the development of International Standards through technical committees established by therespective organization to deal with particular fields of technical a
11、ctivity. ISO and IEC technical committeescollaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, inliaison with ISO and IEC, also take part in the work.International Standards are drafted in accordance with the rules given in the ISO/IEC Direct
12、ives, Part 3.In the field of information technology, ISO 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

14、IEC 11693 was prepared by Joint Technical Committee ISO/IEC JTC 1, Informationtechnology, Subcommittee SC 17, Identification cards and related devices.This second edition cancels and replaces the first edition (ISO/IEC 11693:1994), which has been technically revised.ISO/IEC 11693:2000(E) ISO/IECivIn
15、troductionThis International Standard is one of a series of standards describing the parameters for optical memory cards andthe use of such cards for the storage and interchange of digital data.The standards recognize the existence of different methods for recording and reading information on optica
16、lmemory cards, the characteristics of which are specific to the recording method employed. In general, thesedifferent recording methods will not be compatible with each other. Therefore, the standards are structured toaccommodate the inclusion of existing and future recording methods in a consistent
17、 manner.ISO/IEC 11693 is generic to all optical memory cards. Characteristics which apply to a specific recording methodshall be found in separate standards documents which define the extent of compliance with, addition to, and/ordeviation from, this relevant base document.The users attention is cal
18、led to the possibility that compliance with this International Standard may require use of aninvention covered by patent rights and/or other material covered by copyrights. By publication of this InternationalStandard, no position is taken with respect to the validity of this claim or of any patent
19、rights or copyrights inconnection therewith.1Identification cards Optical memory cards Generalcharacteristics1 ScopeThis International Standard provides information necessary to store data on cards, to read data from cards, and forthe physical, optical, and data interchangeability of optical memory
20、cards in information processing systems.It defines the general characteristics of optical memory cards including card materials, construction, characteristics,dimensions, and test environments which have been determined to be common to all types of optical memory cardsregardless of recording method
21、employed.The intent of this International Standard is to provide necessary information for card manufacturers, card issuersand card users interested in interchanging digital information encoded on optical memory cards.This International Standard can serve as a guide to companies who plan to develop
22、equipment and systems usingoptical memory cards. The data content and use of the cards depend upon the applications developed by eachindustry group.2 Normative referencesThe following normative documents contain provisions which, through reference in this text, constitute provisions ofthis Internati
23、onal Standard. For dated references, subsequent amendments to, or revisions of, any of thesepublications do not apply. However, parties to agreements based on this International Standard are encouraged toinvestigate the possibility of applying the most recent editions of the normative documents indi
