Constant angular velocity (CAV) refers to laser disc operating format in which the disc rotates at a constant speed during play.
CAV permits more special effects (still-frame, slow-motion and fast-motion for example) but this format is somewhat wasteful of disc space. CAV discs are limited to 30 minutes of material on each side of a 12" laser disc.Quelle: Gloria Buenavista - 122470/2006-09-27
