Abstract
A tray-type optical disc drive includes a base unit, an optical disc drive body, a front panel and a disc tray. The disc tray includes at least a retainer and a receiver. The receiver includes a horizontal bearing area, a ramp and a vertical bearing area. The ramp outwardly adjoins the horizontal bearing area while the vertical bearing area outwardly adjoins the ramp. The horizontal bearing area contacts with the outer edge of the disc when the disc is under horizontal disposition. The retainers are disposed on the receiver. When the disc is under vertical disposition, the retainers stop the disc edge for the disc to be positioned. The vertical bearing area and the retainer stop the lower edge of the disc edge. The upper edge of the disc edge leans against the horizontal bearing area.
