Abstract
An optical disc drive and method thereof. The optical disc drive comprises a rotating means, an optical pickup head, a servo unit, and a controller. The rotating means rotates an optical disc. The optical pickup head generates an optical beam to detect defects in a predetermined range on the optical disc. The servo unit, coupled to the optical pickup head, is responsive to an operating parameter to control the optical pickup head. The controller, coupled to the optical pickup head and the servo unit, identifies a defect type based on the defect detection result; and determines the operating parameter of the servo unit according to the defect type.
