Optical pickup tilt control module and method for correcting and adjusting the tilt of an optical pickup

摘要

An optical pickup tilt control module and a method for controlling a tilt value of an optical pickup to reduce the jitter value of a generated reproducing signal. The optical pickup tilt control module includes a reproducing signal generator, a jitter detector, a tilt controller and a tilt actuator. The reproducing signal generator receives a RF signal generated from the optical pickup and generates an EFM signal. The jitter detector receives the EFM signal and detects a jitter value of the EFM signal. The tilt controller generates optimum tilt control values during a correction stage and outputs a tilt control value according to a track position of reproduction data during an adjusting stage. The tilt actuator controls the tilt of the optical pickup according to the tilt control value.
