A method and an apparatus of adjusting the tilt-angle of the lens in the optical pick-up head. The apparatus includes a position detecting unit for detecting a position deviation of the lens against the sled, a parameter generating unit for generating a tilt control parameter according to the position deviation, and a tilt control unit for controlling the lens according to the tilt control parameter so that the lens maintains horizontal with reference to the sled.

Method and apparatus for controlling tilt-angle of lens in optical pick-up head

When recording to an optical disk under zoned constant linear velocity (ZCLV) or partial constant angular velocity (PCAV) control, a plurality of super link points are dynamically set in the packet link areas. In this way, packet units recorded on a track of the optical disk are kept continuous.
