Definitions for "laser disk"
A digital data storage medium consisting of a thin disk onto which the data is impressed by a laser, in the form of a linear sequence of dots; same as optical disk. The data is subsequently read back by the use of a laser beam. See also compact disk.
CAV- constant angular velocity In CAV players the disk rotates at a constant speed and one revolution of the disk corresponds exactly to one frame (two fields). CLV - constant linear velocity In CLV players the rotation speed varies but the speed of the pick up over the disk surface is constant which allows more information to be packed on the outer parts of the disk, hence a longer playing time.
An analog or digital storage medium written and read by laser.
