ABSTRACT:
An optical-disc driving apparatus for an optical disc includes a pickup; a detection unit for detecting a traverse signal by differential push-pull (DPP) detection for every radial tilt angle within a first range, the radial tilt angle being measured between the optical disc and the pickup; a determination unit for determining the radial tilt angle corresponding to a traverse signal within a second range including a maximum value among the detected traverse signals; and a control unit for controlling the orientation of the pickup with respect to the optical disc based on the determined radial tilt angle. The optical-disc driving apparatus controls driving of the optical disc based on the traverse signal by DPP detection generated from a preceding beam, a main beam, and a succeeding beam.
