Method of discriminating optical disc type and apparatus thereof |
摘要 |
A method of discriminating an optical disc type and an apparatus thereof. The method for an optical disc system of recording and/or reproducing an optical disc that includes an optical pickup having a laser diode, an object lens, and a light receiving device, checks a track error signal while moving the object lens to upward/downward, and discriminates an optical disc type by using the magnitude of the checked track error signal. The method and apparatus discriminate the disc type in the initial stage of focusing where the object lens moves to upward/downward.
