A robust optical disc discrimination method which tolerates pick-up head and laser power source deviations
2005
This paper presents a robust optical disc discrimination method which tolerates pick-up head and laser power source deviations. Unlike the prior art techniques, the proposed method uses normalization process to cancel influences caused by deviations of pick-up heads and laser power source so as to minimize the disc discrimination error rate to secure normal disc playback function of an optical disc drive.
