  1. ＤＶＤ−Ｒ／ＲＷ規格の光ディスクのグルーブに記録された再生情報を再生する光ディスク装置であって、
    グルーブに対して読取りを行ってＲＦ信号を生成するＲＦ信号生成部と、
    ウォブル信号に対してＬＰＰを検出するＬＰＰ検出部と、
    前記ＲＦ信号のシンクフレームの先頭に位置する同期パターン部のタイミングで、前記ＬＰＰ検出部によりＬＰＰが検出された場合と検出されなかった場合の前記同期パターン部を夫々ＬＰＰ有同期パターン部とＬＰＰ無同期パターン部として、極性が同一であるＬＰＰ有同期パターン部とＬＰＰ無同期パターン部間で信号レベルの差分を算出する処理を行って差分セットを得る差分算出部と、
    前記差分算出部の算出結果を用いて、前記ＬＰＰ検出部によりＬＰＰが検出されたタイミングの前記ＲＦ信号に対して補正を行う補正実行部とを備えることを特徴とする光ディスク装置。
