    8、ion 12 BS ISO/IEC 11694-4:2008iv 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 Inter

    9、national 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

    10、 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technic

    11、al committee is to prepare International Standards. 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. Attention is dra

    12、wn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 11694-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee

    13、 SC 17, Cards and personal identification. This third edition cancels and replaces the second edition (ISO/IEC 11694-4:2001), which has been technically revised. ISO/IEC 11694 consists of the following parts, under the general title Identification cards Optical memory cards Linear recording method:

    14、Part 1: Physical characteristics Part 2: Dimensions and location of the accessible optical area Part 3: Optical properties and characteristics Part 4: Logical data structures Part 5: Data format for information interchange for applications using ISO/IEC 11694-4, Annex B Part 6: Use of biometrics on

    15、an optical memory card BS ISO/IEC 11694-4:2008v Introduction ISO/IEC 11694 defines the parameters for optical memory cards and the use of such cards for the storage and interchange of digital data. ISO/IEC 11694 recognizes the existence of different methods for recording and reading information on o

    16、ptical 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, ISO/IEC 11694 is structured to accommodate the inclusion of existing and future recording methods in a con

    17、sistent manner. This part of ISO/IEC 11694 is specific to optical memory cards using the linear recording method. Characteristics which apply to other specific recording methods are defined in separate standards documents. This part of ISO/IEC 11694 defines the logical data structures and the extent

    18、 of compliance with, addition to, and/or deviation from the relevant base document ISO/IEC 11693. BS ISO/IEC 11694-4:2008blank1 Identification cards Optical memory cards Linear recording method Part 4: Logical data structures 1 Scope This part of ISO/IEC 11694 defines the logical data structures for

    19、 optical memory cards necessary to allow compatibility and interchange between systems using the linear recording method. 2 Normative references The following referenced documents are indispensible for the application of this document.
