ISO/IEC 16969:1999 pdf free download.lnformation technology - Data interchange on 120 mm optical disk cartridges using +RW format - Capacity: 3,0 Gbytesand 6,0 Gbytes.

4.10 land and groove: A trench-like feature of the disk, applied before the recording ot any information, and used to define the

track location, The groove is located nearer to the entrance surface than the land, The recording is made in the groove.

4.11 mark: A feature of the recordrng layer which may take the form of an amorphous domain, a pit, or any other type or form that

can be sensed by the ophCal system. The pattern of marks and spaces represents the data on the disk.

4.12 phase change: A physical effect by which the area of a recording layer Irradiated by a Laser beam is heated so as to change

from an amorphous state to a crystalline state and vice versa.

4.13 Physical Sector: The smallest addressable part of a track in the Information Zone of a csk that can be accessed independently of other addressable parts of the Zone.

4.14 recording layer: A layer of the disk on which data is written during manufacture and I or use.

4.15 Reed-Solomon code (RS): An error detection and i or correction code.
