【実用新案登録請求の範囲】[Scope of utility model registration request] 直流モータによって磁気ディスクを回転させるよう１こ
した磁気ディスク装置に於て、直流モータとモータ駆動
増巾回路間にそイツ芋ング回路を設け、電源スィッチを
遮断状態にした時に、慣性によって回転する直流モータ
の起電力をスイッチング回路によって負荷回路又は短絡
回路に加えて直流モータを短時間に停止させてなること
を特徴とする磁気ディスク装置。In a magnetic disk drive in which the magnetic disk is rotated by a DC motor, a switching circuit is provided between the DC motor and the motor drive amplification circuit, and when the power switch is turned off, the magnetic disk rotates due to inertia. A magnetic disk drive characterized in that the electromotive force of the DC motor is applied to a load circuit or a short circuit by a switching circuit to stop the DC motor in a short time.
