constant angular velocity; CAV
Technical term used in computing and engineering, especially for optical disc drives (e.g., CD, DVD) where the disc spins at a constant rotational speed. Often abbreviated as CAV.
See also: 線速度一定
This drive uses the constant angular velocity method.
角速度一定と線速度一定の違いを説明してください。
Please explain the difference between constant angular velocity and constant linear velocity.
Constant linear velocity (CLV), where the rotational speed varies to keep the linear speed constant; often contrasted with CAV in optical disc technology.
Compound of 角速度 (angular velocity) and 一定 (constant). A straightforward technical term.
