ABSTRACT:
A magnetic disk drive includes a spindle for rotating a plurality of magnetic disks and a lock mechanism for preventing the spindle from rotating when the magnetic disk drive is not operated. A toothed disk is provided on an axial end of the spindle, and a movable lock arm engageable to teeth of the toothed disk is provided. The lock arm is driven to lock the rotation of the spindle by a solenoid which is energized after a predetermined period of time has elapsed after the electric power of the disk drive is turned off, so that the lock mechanism locks the spindle after the rotation of the spindle and magnetic disks completely stop.
