Abstract: A hard disk drive having a disk storing data, a spindle motor rotating the disk, an actuator having two arms disposed at both sides of the disk, and a disk locking apparatus locking the disk not to rotate by closely contacting a side surface of the disk when the disk stops rotating. A suspension supporting a record/reproduce slider is installed at a first arm disposed at one side surface of the disk. The disk locking apparatus is installed at a second arm disposed at the other side surface of the disk. The disk locking apparatus has a dummy suspension whose one end portion is installed at the second arm and has a predetermined elastic force, and a dummy slider installed at other end portion of the dummy slider, and locking a stopped disk to prevent movement of the stopped disk and damage to bearings of the spindle motor.

Abstract: A disk drive system for contact recording has a flexure beam holding a transducer at one end, the flexure beam being oriented substantially along the direction that the transducer slides on a rigid magnetic disk. The transducer has a protrusion which contacts the disk and separates the rest of the transducer from the moving air film that adjoins the spinning disk, the protrusion containing a magnetic pole structure that communicates with the disk during sliding. A preferred embodiment employs a gimbal structure which allows limited movement of the transducer relative to the flexure beam and three disk-contacting pads extending down from the transducer to make contact with the magnetic disk, at least one of the pads containing a magnetic pole structure and two of the pads trailing the third pad.
