IS 14176 : 2025/ISO/IEC 9660 : 2023 Information Processing - Volume and File Structure of CD-ROM for Information Interchange
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO/IEC 9660 : 2023 'Information processing - Volume and file structure of CD-ROM for information interchange' issued by International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) jointly was adopted by Bureau of Indian Standard on the recommendations of the Computer Hardware, Peripherals, Office Equipment and User Interfaces Sectional Committee and the approval of the Electronics and Information Technology Division Council.
This standard was first published in 1994 to align it with ISO 9660 : 1988. This first revision has been undertaken to take into consideration the developments that have taken place subsequently and also to align with the latest version of ISO/IEC 9660 : 2023
This edition includes the following significant technical changes with respect to the previous edition:
The term “standard for recording” has been removed from 3 as it is no longer considered necessary. Reference to a "standard for recording" have been replaced with cross-references to ISO/IEC 10149;
The enhanced volume descriptor has been added in order to harmonize with the "joliet specification" widely used on PC (see B-1). Specific details are as follows:
a) the volume descriptor version has been changed to indicate the new structure;
b) the file structure version has been changed to indicate the new structure;
c) the limitation in the depth of hierarchy has been lifted;
d) the file identifier has not been separated into components;
e) the file identifier does not have file version numbers;
f) the character used for filling byte positions which are specified to be characters is subject to agreement between the originator and the recipient of the volume;
g) the length of the file identifier has been limited to 207; and
h) the length of a directory identifier has been limited to 207;
Details of modifications for the "joliet specification" have been described in B-2;
Various editorial modifications have been made to bring the document in line with current drafting rules.
The text of ISO/IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
