Glossary

Axial acceleration

Acceleration on the recording layer along with the line perpendicular to the disk reference surface to a specified rotation speed. Axial acceleration is detected by optical means.

Axial displacement

A displacement at a point on the recording layer in a direction perpendicular to the disk reference surface from its original standard position. The standard position on the recording layer is detected optically using the thickness of the protective layer and refraction rate based on the disk reference surface.

Case

A cover of the optical disk. The case protects the disk from being damaged during handling and also allows the operator to exchange disks easily. The case also contains a label, write protection tab, automatic handling support, and media identification hole.

CDB (Command Descriptor Block)

A series of data describing input-output commands. CDB is sent from the initiator to the target.

Clamp area

A ring area on the disk on which a clamp force is applied by the clamp mechanism.

Command

An input-output instruction to the target. Described as CDB.

Control track

A track used to store media parameters and format information required to record and read data to or from the optical disk.

Defect management

In real time, an automatic program used to change the power, focus, tracking of reading and recording if an error is detected and to decide if many error sectors should be discarded. In batch mode, a guideline used to re-record or save the disk.
