APPARATUS AND METHOD FOR CONTROLING TILT OF OPTICAL DISC

摘要

PURPOSE: A tilt control apparatus and method of optical disc is provided to perform tilt control operation optimized for each split outer surface of the optical disc even if the spilt outer surfaces have different eccentric components. CONSTITUTION: A tilt control method of optical disc(10) is as follows. Tilt control to the inner area of the optical disc is performed and an inner circumference tilt correction value is stored. Each split outer surface of the optical disc is performed and outer circumference tilt correction values corresponding to split outer surfaces are stored.
