Abstract

A control system for a disc playing device which facilitates selection of playing of discs by assigning identification codes comprising consecutive numbers to all disc holding grooves of a magazine. A memory of a microcomputer has a first storage area for storing the identification code of the magazine groove positioned as opposed to a disc insertion-discharge portion or playing portion, and a second storage area for storing the identification code of the groove accommodating the disc to be played. The direction of rotation of the magazine is determined by an arithmetic procedure based on the two identification codes stored in the first and second storage areas and on the difference in position between the insertion-discharge portion and the playing portion around the center of the magazine.
