Designing Center Error Control in Optical Disc Drive Systems

概要

論文の詳細を見る
In this paper, the feedback control system for controlling the center error which represents the vibration of the object lens of the pick-up during the movement of the coarse actuator is considered. The center error signal measured from the push-pull signal is corrupted by the track-cross noise, which degrades the control performance. Through the experiments, we discuss a few issues related to the center error control for improving the quality of the compact disc player as an audio-video equipment.
