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 23912 was prepared by ECMA (as ECMA-359) 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 corrected version of ISO/IEC 23912:2005 incorporates the following corrections:
⎯ description of Figure 20 corrected in 14.5.1;
⎯ data for Table 26 corrected in 28.3.2.1;
⎯ label for Figure F.3 corrected in F.4;
⎯ Figure J.1 in J.2 corrected;
⎯ on the third line of page 128 (M.3.1), the words "see Table M.2" replaced by "see Table M.3";
⎯ the text of the last line of page 130 (M.3.1) corrected.

ISO/IEC 23912:2005(E)
Introduction
In June 2001 eleven members proposed to ECMA TC31 to develop a standard for 120 mm and 80 mm
DVD Recordable optical disks using Organic Dye recording technology and TC31 adopted this project.
In April 2004 ten members proposed to TC31 to restart this project and TC31 re-activated the work
that has resulted in this International Standard.
This International Standard specifies two Types of Recordable optical disks, one (Type 1S) making use
of recording on only a single side of the disk and yielding a nominal capacity of 4,70 Gbytes for a 120 mm
disk and 1,46 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 9,4 Gbytes for a 120 mm disk and 2,92 Gbytes for
an 80 mm disk.
