Patent abstract
In an embodiment, an optical disk drive includes a land prepit detection circuit. With such circuit, if the optical disk drive reads a poor-quality disk on which, in terms of signals, LPP-like noises are caused by a defect of a land area, it is possible to increase the noise immunity and LPP detection accuracy of the optical disk drive so that the optical disk drive is capable of successfully detecting LPP without fail.
