METHOD AND DEVICE FOR COMPENSATING TILT OF OPTICAL DISC

摘要

PURPOSE: A method and a device for compensating the tilt of an optical disc are provided to compensate the tilt based on a correlation equation generated by using the inner/outer circumference information data for a measuring position and an inner/outer circumference tilt of the optical disc. CONSTITUTION: An RF amplifier(320) generates a focus error signal and a tracking error signal by the lens-up/down of a pickup(314). A system controller(324) measures the tilt at an inner/outer circumference through the focus error signal and the tracking error signal generated from the RF amplifier, and reads the information data of the inner/the outer circumference at a measuring position of the optical disc. The system controller compensates the tilt for a search target position by generating the correlation equation with use of the tilt data and the position information data for the inner/outer circumference.
