Standard ECMA-338
80 mm (1,46 Gbytes per side) and 120
mm (4,70 Gbytes per side) DVD Re-recordable Disk (DVD-RW)
(December 2002)
This Ecma Standard specifies the mechanical, physical and optical
characteristics of an 80 mm and a 120 mm DVD Re-recordable disk
to enable the interchange of such disks. It specifies the quality
of the pre-recorded, 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 (DVD-RW) disk.
This Ecma Standard specifies:
- 80 mm and 120 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 pre-recorded 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 pre-recorded and unrecorded
areas on the disk, enabling data processing systems to read
the pre-recorded 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 Ecma 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.
