Recording and reproducing method, recording and reproducing device and semiconductor circuit

摘要

An optical disk information recording and reproducing device ( 100 ), which is used for recording and reproducing information on an optical disk ( 10 ), includes a system controller ( 19 ), a tracking control portion ( 15 ), a focus control portion ( 16 ) and an aberration correction portion ( 17 ). The system controller ( 19 ) adjusts a control parameter for recording and reproducing control of the optical disk ( 10 ) by using a tracking error signal TE that is detected from an region ( 30 ) having a wide track pitch on the optical disk ( 10 ). The tracking control portion ( 15 ), the focus control portion ( 16 ) and the aberration correction portion ( 17 ) record and reproduce information on the optical disk ( 10 ) by using the adjusted control parameter.
