noun
Technical term used in computing and engineering, especially in reference to optical disc drives (e.g., CAV vs. CLV).
等角速度方式は、ディスクの回転数を一定に保つ。
The constant angular velocity method keeps the disc's rotational speed constant.
等線速度 (constant linear velocity) is the contrasting method where the linear speed of the disc relative to the read head is kept constant, requiring variable rotational speed.
Compound of 等 (equal, constant) + 角速度 (angular velocity).
