Information technology — Data interchange on 120 mm and 80 mm optical disk using +RW DL format — Capacity: 8,55 Gbytes and 2,66 Gbytes per side (recording speed 2,4X)
ISO/IEC 29642:2009 specifies the mechanical, physical and optical characteristics of 120 mm rewritable optical disks with capacities of 8,55 Gbytes and 17,1 Gbytes. 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 DL. ISO/IEC 29642:2009 also specifies 80 mm disks with capacities of 2,66 Gbytes and 5,32 Gbytes. These disks have the same characteristics as the 120 mm disks, except for some parameters related to the smaller dimensions. All parameters unique for the 80 mm disks are specified in an annex. ISO/IEC 29642:2009 specifies the following: 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; the characteristics of the signals recorded on the disk, thus enabling data processing systems to read the data from the disk. ISO/IEC 29642:2009 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 shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 29642 was prepared by Ecma International (as ECMA-374) 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 second edition cancels and replaces the first edition (ISO/IEC 29642:2007), which has been technically
revised.

Introduction
Ecma Technical Committee TC31 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 TC31 and published by Ecma, almost all of which have also
been adopted by ISO/IEC under the fast-track procedure as International Standards.
In June 2006, a group of companies proposed that TC31 develop a standard for 120 mm dual layer rewritable
optical disks using phase change recording technology and based on ISO/IEC 16448, ISO/IEC 17341 and
ISO/IEC 26925. TC31 adopted this project and started the work that has resulted in this International
Standard.
This International Standard specifies two Types of rewritable optical disks: one (Type S9) making use of
recording on only a single side of the disk and yielding a nominal capacity of 8,55 Gbytes or 2,66 Gbytes per
disk and the other (Type D18) making use of recording on both sides of the disk and yielding a nominal
capacity of 17,1 Gbytes or 5,32 Gbytes per disk.
This International Standard, taken together with a standard for volume and file structure, such as for instance
developed in Ecma Technical Committee TC15, provides the requirements for information interchange
between systems.

INTERNATIONAL STANDARD ISO/IEC 29642:2009(E)
Information technology — Data interchange on 120 mm and
80 mm optical disk using +RW DL format — Capacity:
8,55 Gbytes and 2,66 Gbytes per side (recording speed 2,4X)
1 Scope
This International Standard specifies the mechanical, physical and optical characteristics of 120 mm
rewritable optical disks with capacities of 8,55 Gbytes and 17,1 Gbytes. 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 DL.
This International Standard also specifies 80 mm disks with capacities of 2,66 Gbytes and 5,32 Gbytes. These
disks have the same characteristics as the 120 mm disks, except for some parameters related to the smaller
dimensions. All parameters unique for the 80 mm disks are specified in Annex A.
This International Standard specifies the following:
⎯ two related but different Types of this disk (see Clause 7);
⎯ 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;
⎯ the characteristics of the signals recorded on the disk, thus enabling data processing systems to read the
data from the disk.
This International Standard 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.
2 Conformance
2.1 Optical disk
A claim of conformance with this International Standard shall specify the Type implemented. An optical disk is
in conformance with this International Standard if it meets all mandatory requirements specified for its Type.
2.2 Generating system
A generating system is in conformance with this International Standard if the optical disk it generates is in
accordance with 2.1.
© ISO/IEC 2009 – All rights reserved 1
2.3 Receiving system
A receiving system is in conformance with this International Standard if it is able to handle both Types of
optical disk according to 2.1.
2.4 Compatibility statement
A claim of conformance by a generating or receiving system with this International Standard shall include a
statement listing any other standards supported. This statement shall specify the numbers of the standards,
the optical disk types supported (where appropriate) and whether support includes reading only or both
reading and writing.
