Information technology — Data Interchange on 120 mm and 80 mm Optical Disk using +RW Format — Capacity: 4,7 Gbytes and 1,46 Gbytes per Side (Recording speed up to 4X)
ISO/IEC 17341:2006 specifies the mechanical, physical and optical characteristics of 120 mm rewritable optical disks with capacities of 4,7 GB and 9,4 GB. It specifies the quality of the recorded and unrecorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written read and overwritten many times using the phase change method. These disks are identified as +RW. ISO/IEC 17341:2006 also specifies 80 mm disks with capacities of 1,46 GB and 2,92 GB. These disks have the same characteristics as the 120 mm disks, except for some parameters related to the smaller dimensions. This International Standard specifies: two related but different Types of this disk; the conditions for conformance; the environments in which the disk is to be tested, operated and stored; the mechanical, physical and dimensional characteristics of the disk, so as to provide mechanical interchange between data processing systems; the format of the information on the disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method; and the characteristics of the signals recorded on the disk, thus enabling data processing systems to read the data from the disk. ISO/IEC 17341:2006 provides for the interchange of disks between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems.

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 fields of mutual interest. Other international organizations, governmental
and non-governmental, 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical 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 drawn 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 17341 was prepared by Ecma International (as ECMA-337) 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.
This third edition cancels and replaces the second edition (ISO/IEC 17341:2005), which has been technically
revised.

Introduction
Ecma Technical Committee TC 31 was established in 1984 for the standardization of Optical Disks and
Optical Disk Cartridges (ODC). Since its establishment, the Committee has made major contributions to
ISO/IEC toward the development of International Standards for 80 mm, 90 mm, 120 mm, 300 mm, and
356 mm media. Numerous standards have been developed by TC 31 and published by Ecma, almost all of
which have also been adopted by ISO/IEC under the fast-track procedure as International Standards.
In February 2002, a group of companies proposed to TC 31 to develop a standard for 120 mm rewritable
optical disks using Phase Change recording technology and based on the DVD — Read-Only standard
(ISO/IEC 16448) and the +RW format (ISO/IEC 16969). TC 31 adopted this project and started the work that
resulted in the first edition of ISO/IEC 17341.
This International Standard specifies two Types of rewritable optical disks, one (Type S) making use of
recording on only a single side of the disk and yielding a nominal capacity of 4,7 or 1,46 Gbytes per disk and
the other (Type D) making use of recording on both sides of the disk and yielding a nominal capacity of 9,4 or
2,92 Gbytes per disk.
In April 2003, a proposal was made to TC 31 to update this International Standard for recording speeds up to
four times the Reference velocity. TC 31 adopted this project which has resulted in the second edition of
ISO/IEC 17341.
In February 2005, a proposal was made to TC 31 to update this International Standard to facilitate the
application of the Video Content Protection System.
This International Standard, taken together with a standard for volume and file structure, such as for instance
developed in Ecma Technical Committee TC 15, provides the requirements for information interchange
between systems.
