ISO/IEC 13346-5: 1995(E) OISO/IEC
Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the
specialised system for worldwide Standardisation. National bodies that are members of ISO or IEC participate in the
development of International Standards through technical committees established by the respective Organisation to deal with
particular Felds of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organisations, govemmental and non-governmental, in liaison with ISO and IEC, also take part in this 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 national bodies for voting. Publication of
an International Standard requires approval by at least 75% of the national bodies casting a vote.
International Standard ISO/IEC 13346 was prepared by the European Association for Standardizing Information and
Communication Systems, ECMA, (as Standard ECMA-167) and was adopted, under a special “fast-track procedure ”, by Joint
Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by National Bodies of ISO and
IEC.

Introduction
ISO/IEC 13346 is a volume and file structure Standard for interchanging files and as such, it is a peer to existing volume and
file structure Standards such as ISO 9293 and ISO 9660. It is rather different from those Standards in at least two important
ways. Firstly, it offers much more functionality, mainly because of user needs for increased Character set support and for more
powerful file system features. Secondly, it acknowledges the separate concerns of booting, volume structure and file system
structure. Rather than bundling these different ftmctions together, ISO/IEC 13346 carefully Segregates these functions into
separate Parts and describes in detail how those Parts fit together. It is expected that future volume and file structure
Standards will fit into this framework, rather than building other distinct and incompatible formats.
ISO/IEC 13346 is published in five Parts. Part 1 - general - specifies references, definitions, notations and basic structures
used in the other four Parts. Part 2 - volume and boot block recognition - specifies formats and system requirements for
recognising the volume structures on a medium and booting from a medium. Part 3 - volume structure - specifies how to
record various volume-related entities such as volumes, volume sets and logical volumes. Part 4 - file structure - specifies how
to record and interpret files, both file data and file attributes, and file hierarchies within logical volumes. Part 5 - record
structure - specifies how to record and interpret file data encoded as records.

Information technology - Volume and file structure of write-once and rewritable
media using non-sequential recording for information interchange -
Part 5:
Record structure
Section 1: General
1
Scope
ISO/IEC 13346 specifies a format and associated system requirements for volume and boot block recognition, volume
structure, file structure and record structure for the interchange of information on media between users of information
processing systems.
The media shall be recorded as if the recording of sectors may be done in any Order.
NOTE 1 - The medium is not restricted to being of only one type; the type of medium may be either write once, or read only, or rewritable, or a combination of these
types.
ISO/IEC 13346 consists of the following flve Parts:
Part 1: General
Part 2: Volume and Boot Block Recognition
Part 3: Volume Structure
Part 4: File Structure
Part 5: Record Structure
Annex A - ICB Strategies, is part of ISO/IEC 13346-4.
This Part of ISO/IEC 13346 specifies a format and associated system requirements for record structure by specifling:
-
record structures intended for use when the information constituting a file is required to be interpreted as a set of records;
- the attributes of the records of a file;
-
requirements for the processes which are provided within information processing systems, to enable information to be
interchanged b
