Each tray is provided with a hook and an identification hole indicative of type information of each disc, and an ejector lever for ejecting each tray is provided with a sensor for sensing the information of the identification hole. When the disc package is loaded, the identification of the disc on each tray is known by causing the ejector lever to face sequentially the hooks of the trays.
