Information technology — 120 mm (8,54 Gbytes per side) and 80 mm (2,66 Gbytes per side) DVD re-recordable disk for dual layer (DVD-RW for DL)
ISO/IEC 13170:2010 specifies the mechanical, physical and optical characteristics of a 120 mm and an 80 mm dual layer DVD re-recordable disk to enable the interchange of such disks. It specifies the quality of the embossed, unrecorded and the recorded signals, the format of the data, the format of the information zone, the format of the unrecorded zone, and the recording method, thereby allowing for information interchange by means of such disks. This disk is identified as a DVD re-recordable disk for dual layer (DVD-RW for DL). ISO/IEC 13170:2010 specifies: 120 mm and 80 mm nominal diameter disks that may be either single or double sided; the conditions for conformance; the environments in which the disk is to be operated and stored; the mechanical and physical characteristics of the disk, so as to provide mechanical interchange between data processing systems; the format of the embossed information on an unrecorded disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method used; the format of the data and the recorded information on the disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method used; the characteristics of the signals from embossed and unrecorded areas on the disk, enabling data processing systems to read the embossed information and to write to the disks; the characteristics of the signals recorded on the disk, enabling data processing systems to read the data from the disk. ISO/IEC 13170:2010 provides for interchange of disks between disk drives. Together with an International 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 13170 was prepared by Ecma International (as ECMA-384) 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
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
JTC 1/SC 23 toward the development of International Standards for optical disks. 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. The following Ecma Standards for DVD 120 mm
and 80 mm have been published by Ecma and adopted by ISO/IEC JTC 1. Those standards are based on
original specifications from The DVD Forum.
ISO/IEC 16448 Information technology — 120 mm DVD — Read-only disk
ISO/IEC 16449 Information technology — 80 mm DVD — Read-only disk
ISO/IEC 16824 Information technology — 120 mm DVD rewritable disk (DVD-RAM)
ISO/IEC 16825 Information technology — Case for 120 mm DVD-RAM disks
ISO/IEC 17342 Information technology — 80 mm (1,46 Gbytes per side) and 120 mm (4,70 Gbytes per
side) DVD re-recordable disk (DVD-RW)
ISO/IEC 17592 Information technology — 120 mm (4,7 Gbytes per side) and 80 mm (1,46 Gbytes per
side) DVD rewritable disk (DVD-RAM)
ISO/IEC 17594 Information technology — Cases for 120 mm and 80 mm DVD-RAM disks
ISO/IEC 20563 Information technology — 80 mm (1,23 Gbytes per side) and 120 mm (3,95 Gbytes per
side) DVD-recordable disk (DVD-R)
ISO/IEC 23912 Information technology — 80 mm (1,46 Gbytes per side) and 120 mm (4,70 Gbytes per
side) DVD Recordable Disk (DVD-R)
In April 2007, nine members proposed that TC31 develop a standard for 120 mm and 80 mm dual layer
DVD re-recordable optical disks using Phase Change recording technology. TC31 adopted this
project, which has resulted in this International Standard.
This International Standard specifies two Types of dual layer re-recordable optical disks: one (Type 1S)
making use of recording on only a single side of the disk and yielding a nominal capacity of 8,54 Gbytes for a
120 mm disk and 2,66 Gbytes for an 80 mm disk, the other (Type 2S) making use of recording on both sides
of the disk and yielding a nominal capacity of 17,08 Gbytes for a 120 mm disk and 5,32 Gbytes for an 80 mm
disk.

INTERNATIONAL STANDARD ISO/IEC 13170:2009(E)
Information technology — 120 mm (8,54 Gbytes per side) and
80 mm (2,66 Gbytes per side) DVD re-recordable disk for dual
layer (DVD-RW for DL)
1 Scope
This International Standard specifies the mechanical, physical and optical characteristics of a 120 mm and an
80 mm dual layer DVD re-recordable disk to enable the interchange of such disks. It specifies the quality of
the embossed, unrecorded and the recorded signals, the format of the data, the format of the information zone,
the format of the unrecorded zone, and the recording method, thereby allowing for information interchange by
means of such disks. This disk is identified as a DVD re-recordable disk for dual layer (DVD-RW for DL).
This International Standard specifies:
− 120 mm and 80 mm nominal diameter disks that may be either single or double sided;
− the conditions for conformance;
− the environments in which the disk is to be operated and stored;
− the mechanical and physical characteristics of the disk, so as to provide mechanical interchange between
data processing systems;
− the format of the embossed information on an unrecorded disk, including the physical disposition of the
tracks and sectors, the error correcting codes and the coding method used;
− the format of the data and the recorded information on the disk, including the physical disposition of the
tracks and sectors, the error correcting codes and the coding method used;
− the characteristics of the signals from embossed and unrecorded areas on the disk, enabling data
processing systems to read the embossed information and to write to the disks;
− the characteristics of the signals recorded on the disk, enabling data processing systems to read the data
from the disk.
This International Standard provides for interchange of disks between 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 shall specify the type of the disk, i.e. its size and whether it is single-sided or double
sided. An optical disk shall be in conformance with this International Standard if it meets the mandatory
requirements specified for this type.

2.2 Generating system
A generating system shall be in conformance with this International Standard if the optical disk it generates is
in accordance with 2.1.
2.3 Receiving system
A receiving system shall be in conformance with this International Standard if it is able to handle an optical
disk according to 2.1.
