Standard ECMA-330
120 mm (4,7 Gbytes per side) and 80 mm
(1,46 Gbytes per side) DVD Rewritable Disk (DVD-RAM)
3rd edition (June 2005)
This Ecma Standard specifies the mechanical, physical and optical
characteristics of an optical disk, identified as DVD Rewritable
Disk (DVD-RAM), to enable interchange of such disks. It specifies
the quality of the recorded 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. Two Types are specified
that differ only by their diameter of 120 mm and 80 mm, and the
resulting difference of capacity.
This Ecma Standard specifies:
- 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 Ecma 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. The optical disks specified by this Ecma Standard
may be enclosed in cases as specified in Standard ECMA-331.
