18、1 All rights reserved vIntroductionThis part of ISO/IEC 11694 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 readi
19、ng information on opticalmemory 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
20、 methods in a consistent manner.This part of ISO/IEC 11694 is specific to optical memory cards using the linear recording method. Characteristicswhich apply to other specific recording methods shall be found in separate standards documents.This part of ISO/IEC 11694 defines the logical data structur
21、es and the extent of compliance with, addition to, and/ordeviation from the relevant base document ISO/IEC 11693.INTERNATIONAL STANDARD ISO/IEC 11694-4:2001(E) ISO/IEC 2001 All rights reserved 1Identification cards Optical memory cards Linear recordingmethod Part 4:Logical data structures1 ScopeThis
