ECMA - European Association for Standardizing Information and Communication Systems
Scope
This Ecma Standard specifies optical disk formats that provide parallel read/write methods with written data divided among 5 disks. This Ecma Standard specifies two types of optical disk formats: - Non-parity disk type: This type allows for read/write operations on all user data divided among 5 disks. - Parity disk type: This type allows for read/write operations on all user data divided among 4 disks and for read/write operations on parity data from/to 1 disk. This Ecma Standard specifies the read/write area and the data structure.
