发明名称 Method of identifying a type of an optical disc and the device therefor
摘要 A method of identifying a type of an optical disc applied in an optical drive is provided. The optical drive at least comprises an optical pickup head. First, move the optical pickup head continually from an initial position. Then, emit a light beam on an optical disc continually and receive a reflected light beam from the optical disc to generate a servo signal. Next, detect a waveform pattern of the servo signal continually to determine whether the waveform pattern of the servo signal changes, if so, the optical disc is identified as a Digital Video Disk-Random Access Memory (DVD-RAM).
