28 June 1999 Track center servo and radial tilt servo system for DVD-RAM disc

To increase optical disc capacity, the track pitch becomes narrower. This necessitates a higher-accuracy for track servo. However, with the push-pull track error detection, the standard error detection for rewritable optical disc, detection error occurs due to disc radial tilt. The authors propose new method of a track center detection method that detects track center more accurately than the push-pull track error detection method, and develop a track center servo and radial tilt servo system based on this detection method.
