摘要： An optical disk device is provided in which stable operation is realized even when an offset amount of a signal to be used for servo control changes due to environmental variations. The optical disk device generates a signal for servo control based on signals corresponding to a reflected light of a laser light irradiated to an optical disk, and detects an offset superimposed on a signal for the servo control. The optical disk device compensates the amount of the adjusted offset which has been set up so as to reduce the offset amount in initial setting for light detection corresponding to an optical disk loaded, according to the amount of change of the offset amount detected, adjusts the signal to be used for the servo control based on the amount of the offset control after the compensation, and performs the servo control based on the adjusted signal.

摘要： A tilt compensating device and method of performing normal tilt compensation in the event of a servo emergency which may occur during reproduction of data from an optical recording medium are provided. The tilt compensating device includes: an optical pickup; a tilt adjusting unit that adjusts a tilt angle of the optical pickup; a jitter detecting unit that detects an amount of jitter in a reproduction signal output from the optical pickup; and a controlling unit that monitors speed at which the optical recording medium operates using a phase-locked loop (PLL) signal generated from the reproduction signal and the degree of focus of the optical pickup, performs an operation to return to a normal state if any abnormality occurs, and controls operation of the tilt adjusting unit by comparing an amount of jitter detected at regular intervals against a reference. The present invention provides more stable tilt compensation compared to a conventional approach controlling a tilt driver in real time while monitoring jitter, thus improving disk reproduction capability.
