Abstract: A sub-ambient pressure, air bearing slider is disclosed for positioning a magnetic read/write head proximately to a rotating disk. The slider includes first and second rails extending along the side of the slider facing the rotating disk from a leading edge of the slider to a trailing edge of the slider. Each rail has a thigh region extending at an angle from the leading edge to a lateral side of the slider, a foot region extending at an angle from a lateral side of the slider toward the trailing edge of the slider, and a knee region at a lateral side of the slider coupled between the foot and thigh regions. Recesses are provided to shape the first and second rails. A central recess provides a volume for sub-ambient pressure. One or more tails can be placed within the central region to prevent the shifting of pressure completely to one side of the slider. The design of the first and second rails leads to a more uniform flying height for the slider and magnetic head over all tracks of the disk.

Abstract: A disk drive is provided for flying at low flying heights, for example 2 1/2 mu ''. The disk drive includes an adhesive-bonded slider and head suspension design which does not lose its crown or camber with a change in temperature. In a preferred embodiment, the adhesive is applied at discrete points. It was found that applying the adhesive in this manner was sufficient to securely bond the slider to the flexure tongue and resulted in relatively little change in the crown or camber geometry over a wide range of temperatures.

Abstract: An improved slider (18) with controlled fly height and decreased sensitivity to externally applied roll moments. The slider includes two rails (100, 112), one of the rails (100) having transverse contours (102, 104) providing transverse pressure contourization or edge blend, and the other rail (112) having a wide air bearing surface located at the edge of the slider body for maximizing the distance between the rails (100, 112). The combination of the two rails results in a stiffer slider.

Abstract: Disclosed is a slider with an air bearing surface for flying a magnetic transducer on an air lubrication film over a moving recording medium. The air bearing surface allows the slider to fly at a close and substantially uniform height over the disk surface regardless of the skew angle of the air flow. The slider has a pair of nonidentical, nonsymmetrical rails disposed about the longitudinal axis of the slider, which through the viscous effects of the air flow, provide the air lubrication film when the recording medium is in motion.

Abstract: A floating head slider for a disk driving apparatus, which floats above a disk-like recording medium when this medium is rotated. The head slider includes an air lubrication surface formed on the surface opposed to the disk-like recording medium; a tapered portion on the air inflow side of the air lubrication surface; a recess along the center line extending from the air inflow side of the air lubrication surface to the air outflow side, the recess having the air inflow side thereof closed and the air outflow side thereof open and having a predetermined depth to generate a negative pressure; and a groove extending from the recess to the end of the air inflow side of the air lubrication surface along the center line, and being wider than the recess which divides the air lubrication surface but having the same depth. This head slider can float a predetermined distance above the surface of the disk recording medium in a stable state due to the positive pressure occurring on the air lubrication surface and the surface of the disk-like recording medium driven for rotation and the negative pressure generated by the recess.
