In order to permit a disc to be laid easily on a disc tray in a disc device movable along guide rails fitted into the disc device and having a circular recess made on its upper surface even though the tray is not fully pulled out from the cabinet, the circular recess has a disc-bearing surface on which a disc is to be laid, and the disc-bearing surface has a recess on its rear side, thereby permitting a disc to be inclined and inserted deep into the space between the front overhung of the cabinet and the unexposed area of the disc-bearing surface while holding the disc in the most stable way with the first finger inserted in the center hole and with the thumb applied to the circumference of the disc.
