Optical disc device and method of controlling the same

A method of controlling an optical disc device, the optical disc device including 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, a driving unit actuating the lever member, and a diameter detector detecting the diameter of the disc, the method comprising:

• detecting a diameter of a disc inserted into the optical disc device using the diameter detector;
• moving the lever member along a path which is dependent on the diameter of the disc so as to load 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;
• escaping the lever member from an edge of the disc to allow writing/reading data to/from the disc to be performed;
• and
• writing/reading data to/from the disc.
