Abstract
A disk player providing random disk or piece selection upon turning on of the power supply. According to one aspect of the invention, a piece on an available disk is randomly selected as soon as the disk player is turned on. According to another aspect of the invention, particularly applicable to multi-disk players, the random number is formed by a counter running at a fast rate. When the power is turned on, the counter is started and a mechanical component begins movement toward another position. Only when the component is detected to have arrived, is the counter read to provide the random number for disk or piece selection.
