Data Interchange on 60 mm Read-Only ODC
- Capacity: 1,8 Gbytes (UMDTM)
This Ecma Standard specifies the mechanical, physical and optical
characteristics of a 60 mm, read-only ODC having a maximum capacity
of 1,8 Gbytes. It specifies the physical format, the quality of
the recorded signals, the format of the data and its modulation
method, thereby allowing for information interchange by means
of such ODCs.
This Ecma standard specifies two types of ODCs, Type A and Type
- Type A: Single layer disk with maximum recorded capacity of
- Type B: Dual layer disk with maximum recorded capacity of
Information interchange between systems also requires, at a minimum,
agreement between the interchange parties upon the interchange
code(s) and the specifications of the structure and labeling of
the information on the interchanged ODCs.
