Constant Linear Velocity - Constant Angular Acceleration

Constant Angular Acceleration (CAA) is a variant of CLV that was used on the Laserdisc format. The initial specification of CLV (as it applied to laserdisc) resulted in several playback artifacts to be present in the audio/video portion as well as compatibility problems with laserdisc players as produced by different manufacturers.

In the mid 1980s, Pioneer Electronics introduced the CAA scheme where the speed in rotation of the laserdisc was lowered in steps and eliminated most playback artifacts and compatibility problems. Since its introduction, most manufacturers of laserdiscs adopted the CAA format but still referred to their CAA-encoded product as CLV.
