Abstract
A cam member, having a cam groove on its outer surface, is slidably mounted on a rotating shaft to allow for movement of disk holders between a playback position and a stored position. In one embodiment, the cam groove is continuous about the cam member, making two complete rotations around the cam member. When a first disk holder is at the playback position, the cam groove engages the second disk holder at the stored position. When the second disk holder is selected to be played, rotation of the cam member causes the first disk holder to move to a stored position on an opposite end of the cam member while the second disk holder is in the playback position. The overall height required for such a disk holding device is constant, providing for a multiple disk playback device with minimal height requirements.
