==Constant angular acceleration== '''Constant angular acceleration''' ('''CAA''') is a variant of CLV that is used on the LaserDisc format. The initial specification of CLV (as it applies to LaserDisc) results in several playback artifacts being present in the audio/video portion as well as compatibility problems with LaserDisc players produced by different manufacturers. In the mid 1980s, Pioneer Electronics introduced the CAA scheme, where the rotation speed of the LaserDisc was lowered in steps. This 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.
