  • Publication number: 20110170387
    Abstract: An optical disc apparatus and a control method for the optical disc apparatus are provided. A control method for an optical disc apparatus according to one embodiment of the present invention may comprise rotating a disc through a spindle motor if a type of a disc loaded in the optical disc apparatus is determined; and carrying out servo operation which can be processed irrespective of rotation speed of the disc while checking whether the rotation speed of the disc equals a predetermined speed. Servo operation which can be processed independently of the rotation speed of the disc can correspond to operation related to focusing servo and additionally to operation related to tracking servo. Therefore, since the time the user has to wait for requested video, music, or data to be extracted after the user has inserted a medium is reduced, user convenience can be improved.
