Abstract
This tilt correcting method includes the step of monitoring jitter values while adjusting a turntable or guide rail after a wobble disc is placed on the turntable. Thereafter, it is determined whether the depths of valleys of monitored jitter values are different, it is determined that the reference tilt is a radial tilt if it is determined that the depths of valleys of the monitored jitter values are different, and the radial tilt is corrected. If it is determined that the depths of valleys of the monitored jitter values are not different, it is determined whether the heights of peaks of the monitored jitter values are different, it is determined that the reference tilt is a tangential tilt if it is determined that the heights of peaks of the monitored jitter values are different, and the tangential tilt is corrected.
