摘要： Techniques of the present invention include detecting a touchdown between a read/write head of a disk drive and a surface of a magnetic disk using multiple touchdown sensors located at an air-bearing surface (ABS). The multiple sensors increase the likelihood that a touchdown event—i.e., a portion of the ABS of the head contacting the underlying magnetic disk surface—will be detected. During touchdown, the portion of the head contacting the magnetic disk generates frictional heat which changes a characteristic (e.g., the electrical resistance) of at least one of the sensors located at the ABS. When the sensors are connected to a detection circuit, the changing characteristic may be monitored to identify a touchdown event. The touchdown sensors may be, for example, electrically connected in either series or parallel to the detection circuit. Thus, as long as the electrical resistance of one of the sensors is changed, a touchdown event may be detected.

摘要： 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.

摘要： 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.

摘要： A method for forming a head gimbal assembly in which the head gimbal assembly and a frame are formed from a continuous piece of laminated material comprised of a first layer, a second layer and a third layer. A plurality of electrical lines are formed in the third layer of the head gimbal assembly and a plurality of electrical line extensions are formed in the third layer of the frame. The slider is positioned at an angle to the frame and a plurality of termination pads on the slider are bonded to the electrical lines. The frame is partially separated from the head gimbal assembly and the relative position of the slider to the head gimbal assembly is changed by an amount sufficient to separate the plurality of electrical lines from the plurality of electrical line extensions.

摘要： A suspension for use in a magnetic disk drive comprised of a flexible load beam and a slider. The flexible load beam is comprised of a two-layer laminate and air bearing structure is formed in one of the layers. Part of the flexible load beam rests on a data storage disk when the disk is not rotating. When the disk begins rotating, the air bearing structure causes the load beam to fly above the surface of the disk at a first flying height. Similarly, when the disk begins rotating, the air bearing surface of the slider causes the slider to fly above the surface of the disk at a second flying height. Typically, the first flying height is about ten times greater than the second flying height.
