  • Patent number: 7840972
    Abstract: The optical disc device includes a main unit rotating a turntable when a disc is coupled to the turntable and including an optical pick-up unit writing/reading data to/from the disc; a lever member guiding the disc to load the disc to a position at which a center of the disc is aligned with a center of the turntable and reversely guiding the disc to unload the disc, the lever member being capable of loading/unloading discs having various diameters; and a driving unit actuating the lever member. The method of controlling the optical disc device includes detecting a diameter of a disc; loading the disc to a position at which a center of the disc is aligned with the center of the turntable; coupling the disc to the turntable; and moving the lever member away from the disc to allow writing/reading data to/from the disc to be performed.
