  • Head slider and hard disk drive
    Patent number: 8493688
    Abstract: A head slider for a disk drive storage device. The head slider is adapted to fly at the target height above the disk, reduce contamination by preventing particles from being trapped under the head slider, fly well in helium at low velocity and obtain a manufacturing tolerance so that multiple head sliders may be produced and function properly. The head slider has an internal cavity that is substantially enclosed by the air bearing surface. There are two gaps in the air bearing surface that are misaligned relative to the leading edge. The gaps aid in preventing particles from entering the cavity.
    Type: Grant

  • SERVO WRITE ROBUST AND GOOD ALTITUDE PERFORMANCE ABS
    Publication number: 20120099225
    Abstract: A head slider for a disk drive storage device. In general, the head slider should fly at the target height above the disk without crashing onto the hard disk. The head slider has an outside flange that encloses a plateau and an inside flange that encloses a plateau. The two plateaus may have the same surface area or the outside plateau may have a greater surface area. Because of the design of the outside flange, the likelihood that the head slider will crash on the hard disk is reduced.
