A disc record caddy comprises a pair of substantially flat circular covers releasably held in channels defined along the inside rim of an expandable circular ring. Spring elements bias the ring into a contracted shape to radially restrain a disc retained between the pair of covers. A platform, mounted on a base of a disc record player system, horizontally supports the caddy in an elevated position over a turntable of the system and includes means for expanding the ring to release the covers. A turntable spindle incorporates a lowering/lifting mechanism which lowers the cover nearest the turntable and the disc supported thereon onto the turntable for record playback purposes, the other cover being retained at the platform level by the radially inward extension of the land defined between the ring channels. At the termination of record playback, the disc and the supporting cover are lifted up to platform level and the ring is allowed to return to the contracted shape thereby enclosing the disc between the two covers. The expanding means and the lowering/lifting mechanism are actuated in response to the movement of a player lid.
