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
Felds of mutual interest. Other international organizations, govemmental and
non-govemmental, 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. Draft International Standards adopted by
the joint technical committee are circulated to the national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the
national bodies casting a vote.
International Standard ISO/IEC 11694-4 was prepared by Joint Technical
Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 17,

Introduction
This part of ISO/IEC 11694 is one of a series of Standards describing the
Parameters for Optical memory cards and the use of such cards for the storage
and interchange of digital data.
The Standards recognize the existente 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 Standards are
structured to accommodate the inclusion of existing and future recording
methods in a consistent 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 shall be found in separate Standards documents.
This part of ISO/IEC 11694 defmes the logical data structures and the extent of
compliance with, addition to, and/or deviation from the relevant base document
ISO/IEC 11693.
The user ’s attention is called to the possibility that compliance with this part of
ISO/IEC 11694 may require use of an invention covered by patent rights and/or
other material covered by Copyrights. By publication of this part of ISO/IEC
11694, no Position is taken with respect to the validity of this Claim or of any
patent rights or Copyrights in connection therewith.
