Abstract:
1. An apparatus which compensates for a tilt in an optical recording medium drive for an optical recording medium, the apparatus comprising: an optical pickup; a tilt adjuster which adjusts the tilt of the optical pickup; a jitter detector which detects a jittering amount of a playing signal generated from the optical pickup; and a tilt controller which controls operations of the tilt adjuster so as to have the jittering amount become minimum by comparing the jittering amount detected before a seek operation and a first jittering reference value, and comparing the jittering amount detected after the seek operation and a second jittering reference value, wherein in response to the reproduction of the content of the optical recording medium beyond a fixed value, the tilt controller resumes an operation of the optical recording medium after performing a tilt compensation by comparing the jittering amount detected where a predetermined target track is reached and a third jittering reference value.
