Patent ID: 7065020

Claim:
An apparatus which compensates for tilt in an optical recording medium driver which drives an optical recording medium, the apparatus comprising: an optical pickup unit to generate a reproduction signal using the optical recording medium; a tilt adjuster to adjust a tilt of the optical pickup unit; a jitter detector to detect an amount of jitter in the reproduction signal; and a tilt controller which, before performing tilt compensation and when the detected amount of the jitter detected over a certain period of time exceeds a reference value during reproduction of the optical recording medium, controls the tilt compensation to be in a direction in which the amount of the jitter decreases after adjusting an operational direction of the tilt adjuster to be in a direction towards/away from a track of the optical recording medium to be reproduced, wherein the reference value comprises: a first reference value where the detected amount of jitter occurs after a seek operation, and a second reference value if the detected amount of jitter occurs where no seek operation is performed.
