A disc drive apparatus according to the present invention has a tray formed of an optically transparent material and has disc receiving portions. The tray is movable in an ejection and a retraction direction with respect to a casing. A light source is mounted inside the tray at the ejection direction side thereof. The light source emits light toward the ejection direction of the tray to cause the light to propagate within the optically transparent material from the retraction direction side through the ejection direction side of the tray with respect to the disc receiving portion.
