Optical disc device capable of compensating for skew of optical pickup and method thereof

摘要

An optical disc device capable of recording/reproducing data in an optical disc. The optical disc device includes an optical pickup unit for scanning a laser signal onto a specified area of an optical disc, a skew adjustment unit for changing a skew of the optical pickup unit, a signal detection unit for detecting a signal being reproduced from the optical disc by the laser signal, a jitter detection unit for calculating a jitter of the signal detected by the signal detection unit, and a control unit for controlling the skew adjustment unit to compensate for the skew of the optical pickup unit so that the compensated skew of the optical pickup unit becomes the skew that corresponds to the minimum jitter. The optical disc device can minimize a jitter by compensating for the skew so that the skew is in an optimum state.
