Abstract: An autochanger type optical compact disc player includes a disc tray for holding a large number of discs in close proximity, a disc playback section and a disc transferring section for transferring the disc between the disc tray and the disc playback section. The disc tray includes a plurality of disc holding grooves and partition walls for dividing the disc holding grooves from each other. The bottoms of the disc holding grooves are curved in an arc of a radius corresponding to the radius of the discs, and the upper edges of the partition walls incline toward the direction of movement of the discs into the disc holding grooves with respect to the tangent of the periphery of a disc at any point where the periphery of the disc crosses with the upper edges.
