Abstract

　本発明の光ディスク装置は、情報記録面を有する光ディスク１を載置し、回転させるディスク回転機構２と、係合部を含み、前記情報記録面に光ビームを照射することにより、情報の記録および情報の再生の少なくとも一方を行う光ピックアップ３と、前記光ピックアップを回動可能に支持し、前記ディスク回転機構が設けられたベース本体１３と、前記ベース本体に支持されており、前記光ピックアップを回動させる駆動力を発生する駆動源５と、前記ベース本体に支持されており、ウォームを含み、前記係合部と係合することによって、前記駆動源の駆動力を前記光ピックアップに伝達し、前記光ピックアップを回動させる駆動力伝達機構６１０とを備え、前記係合部と前記光ピックアップの回動軸との距離は、前記光ピックアップ全体の重心と前記光ピックアップの回動軸との距離よりも長くなっている。
