- 回転駆動される記録媒体と、
前記記録媒体に対向するように配置されるスライダと、
前記スライダを前記記録媒体に対して位置決めする位置決め装置とを備えた磁気ディスク装置であって、
前記記録媒体は、前記スライダに対向する表面を有し、この表面には液体潤滑剤よりなる膜は配置されておらず、
前記スライダは、前記記録媒体に対向する媒体対向面およびこの媒体対向面の近傍に配置された薄膜磁気ヘッド素子を含むスライダ本体と、前記媒体対向面を保護する保護膜とを有し、
前記保護膜は、テトラヘドラル・アモルファス・カーボン膜によって形成され、
前記位置決め装置は、前記記録媒体が停止しているときには前記スライダを記録媒体の表面から退避させ、前記記録媒体が回転しているときには前記スライダを記録媒体の表面に対向させ、
磁気ディスク装置は、更に、前記記録媒体の表面と前記薄膜磁気ヘッド素子との間の距離を制御する距離制御装置を備え、
前記薄膜磁気ヘッド素子は、前記記録媒体に情報を記録する記録素子と、前記記録媒体に記録された情報を再生する再生素子とを有し、
前記距離制御装置は、前記記録素子による記録動作時および前記再生素子による再生動作時に、記録動作も再生動作も行なわれないときに比べて、前記記録媒体の表面と前記薄膜磁気ヘッド素子との間の距離を小さくすることを特徴とする磁気ディスク装置。 - 前記距離制御装置は、前記スライダ本体に内蔵された発熱部を有することを特徴とする請求項1記載の磁気ディスク装置。
- 前記記録媒体は、磁性層と、この磁性層を保護する固体の保護層とを有し、前記保護層が前記表面に露出していることを特徴とする請求項1または2記載の磁気ディスク装置。
