Claims

[Scope of utility model registration request]

A pivot is provided outside the rotation range of the magnetic disk parallel to the central axis of the magnetic disk, an arm is provided on the pivot that can be swung around the pivot by a drive mechanism, and the magnetic disk is attached to the tip of the arm. In a magnetic disk device equipped with a magnetic head that levitates from the surface of the magnetic disk as the disk rotates to perform reading and writing to the magnetic disk, when the drive mechanism is not operating, the magnetic head moves from the outer circumference to the inner circumference of the magnetic disk. a magnetic head return mechanism that moves and returns the magnetic head to a predetermined position and engages the arm to separate the magnetic head from the magnetic disk surface; and a magnetic head return mechanism that moves the magnetic head outside the magnetic disk when the drive mechanism is activated. 1. A magnetic disk device comprising: a locking mechanism that locks the return mechanism and releases the lock of the magnetic head return mechanism when the drive mechanism is inactive.
