ABSTRACT:
A magazine having a plurality of reset detecting portions arranged concentrically with the magazine and corresponding to disk accommodating spaces having respective predetermined identification numbers. A position index group is disposed between each two adjacent reset detecting portions for detecting the identification number of the particular disk space to which the reset detecting portion, toward the direction of rotation of the magazine, of the two portions corresponds. A sensor is provided on the path of rotation of the magazine on a chassis for detecting the reset detecting portions and position index groups. The sensor is connected to a processor for storing the identification number of the disk space as positioned in alignment with a path of movement of a disk. When the power source is turned on initially, the processor rotates the magazine temporarily, and detects from the number of recesses detected by a sensor the identification number of the disk space corresponding to the reset detecting portion subsequently detected by the sensor.
