   - **Optical Ablation**. A permanent recording mechanism used in early [[extras:glossary#worm|WORM]] optical disk systems, where data is written by physically removing or altering the recording layer of the media.
+===== CAV =====
+  - **Constant Angular Velocity**. A sector arrangement format in which data sectors are positioned at fixed angular intervals around a disk, maintaining a constant rotational speed. Sectors typically have lower linear data density on tracks farther from the center.

+===== CLV =====
+  - **Constant Linear Velocity**. A sector arrangement format in which the disk's rotational speed varies with the read/write head's position to maintain a constant linear velocity. Data is typically recorded at a consistent linear density, maintaining approximately the same bit spacing along the track.
