ABSTRACT:
A mechanism for fixing a magnetic head of a magnetic disk drive in place over the parking area of a recording medium when the disk drive is not in operation. The head records or reproduces data in or out of the data storage area of the medium. When the disk drive is not operated, a magnet and a magnetic piece cooperate to retain the head above the parking area of the medium. A yoke adjoins the side of the magnet for absorbing magnetic lines of force issuing from the magnet, so that the magnetic lines of force may not act on the magnetic piece when the head records or reproduces data.
