Abstract
A compact disk changer includes a magazine having an inner body and an outer body that are rotatable independently of one another about a common axis of rotation. The inner and outer bodies are slideably interconnected by a helical member so that relative rotation between the bodies in a first direction increases the axial spacing between them and relative rotation in a second direction decreases the axial spacing. This construction reduces the size of the changer and does not require precision tolerances between moving parts. A plurality of compact discs are stacked within the magazine, and each disk is supported by a disk holder. When the disk at the top or end of the stack is to be played, relative rotation between the inner and outer bodies creates an axially extending space, adjacent the selected disk and a playing mechanism is inserted into that space. When a disk at any other position within the stack is to be played, the disk holder is engaged and the inner and outer bodies are rotated with respect to one another so that the disk holder immediately below the engaged disk holder is axially displaced with respect to the disk to be played. This creates a space into which the playing mechanism is inserted.
