、これらのヘッドとヘッドパッドとの対により上記ディ
スク状記録媒体を挾み付けるように上記ヘッドあるいは
ヘッドパッドの少なくとも一方を機械的に駆動する駆動
手段と、上記ディスク状記録媒体の装着時で上記モータ
の回転中に上記駆動手段を駆動状態とする回路部を備え
、上記ディスク状記録媒体の装着に応じて上記ヘッドと

決めすることを特徴とする回転ディスク装置。A disc-shaped recording medium in which a rotation drive pin insertion hole is formed at a position eccentric from the rotation center position, and a rotation drive pin inserted into at least the rotation drive pin insertion hole to rotationally drive the disc-shaped recording medium. A motor having a drive pin, a pair of a recording or reproducing head and a head pad that are arranged opposite to each other with the disk-shaped recording medium in between, and a pair of these heads and head pads that sandwich the disk-shaped recording medium. a driving means for mechanically driving at least one of the head or the head pad; and a circuit section for driving the driving means while the motor is rotating when the disc-shaped recording medium is mounted; When the recording medium is mounted, the pair of head and head pad clamps the disc-shaped recording medium and applies a rotational load, thereby moving the rotational driving pin to the rotational reference angular position of the rotational driving pin insertion hole. A rotating disk device characterized by positioning.
