Title:
トラッキング信号生成装置及び方法、再生装置及び方法、並びにコンピュータプログラム
Document Type and Number:
Japanese Patent JP4884533
Kind Code:
B2
Abstract:
A tracking signal generating apparatus is provided with: a reading device for reading reflected light of a laser beam applied onto a recording medium, thereby obtaining a resulting read signal; an amplitude-limiting device for limiting an amplitude level of the read signal by a predetermined amplitude value, thereby obtaining an amplitude limit signal; a filtering device for performing a high-frequency emphasis filtering process on the amplitude limit signal, thereby obtaining an equalization-corrected signal; and a generating device for performing a phase comparison process on the equalization-corrected signal, thereby generating the tracking signal.
