Abstract

　光ディスク用信号処理装置(200)は、トラッキングエラー信号に基づいて光ピックアップ(100)の収束レンズ(103)の位置を制御するトラッキング制御と、トラッキング制御を停止した状態で光ディスク(500)の半径方向に光ピックアップ(100)の収束レンズ(103)を移動させるトラックジャンプ動作とを行う。ゲイン増加量計算部(209)は、トラックジャンプ時における光ディスク(500)の偏心速度に基づいて、トラッキング制御系のループゲインの増加量を求める。トラックジャンプ動作後、トラッキング制御系のループゲインがゲイン増加量計算部(209)において求められた増加量分増加した状態で、トラッキング制御が行われる。
