Patent ID: 7283437

Claim:
A tilt compensating device in an apparatus utilizing an optical recording medium, the tilt compensating device comprising: an optical pickup; a tilt driver that adjusts a tilt angle of the optical pickup; a jitter detector that detects an amount of jitter in a reproduction signal output from the optical pickup; and a controller that monitors a speed at which the optical recording medium operates using a phase-locked loop (PLL) signal generated from the reproduction signal, and a 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 driver by comparing an amount of jitter detected at regular intervals against a first reference amount of jitter, wherein if a focus circuit is unlocked while performing tilt compensation by operating the tilt driver, the controller reduces a maximum tilt position of the tilt driver and controls the operation of the tilt driver so that jitter detected at a reset position is minimized.
