An optical disc drive includes a housing with a protrusion and a tray capable of sliding in and out of the housing. The tray includes a first surface, and a second surface opposite to the first surface. The first surface is partially recessed to form a receiving space for accommodating an optical disc. The second surface defines a channel, and forms a blocking portion at one end of the channel. The protrusion slides in the channel to guide the tray to slide in and out of the housing, and cooperates with the channel to prevent the tray from vibrating. When the tray is fully extended from the housing, the protrusion is located at the end of the channel forming the blocking portion, thus the protrusion is blocked by the blocking portion from sliding too far so that the tray is prevented from sliding off the housing.
