  • Patent number: 8477458
    Abstract: An apparatus and associated method for a slider pad that allows for contact to be mitigated without plastic deformation. Various embodiments of the present invention are generally directed to a slider that presents a transducer and has at least one air bearing surface (ABS) feature. The ABS feature comprises a pair of sidewalls spaced a distance X apart. A pad is deposited on the ABS feature so that the pad comprises a hemispherical cross-section and has a circumferential diameter greater than X.
    Type: Grant

The ABS feature comprises a pair of sidewalls spaced a distance X apart. A pad is deposited on the ABS feature so that the pad comprises a hemispherical cross-section and has a circumferential diameter greater than X. As configured, the pad may mitigate contact between the pad and a media surface with elastic deformation.

  • Patent number: 6608735
    Abstract: An air bearing slider includes an asymmetric taper for control of pressurization and suction force formation. The asymmetric taper is disposed on an edge of a slider to accommodate for the speed differential across the disc radial direction, thereby improving take-off performance, reducing sensitivity to skew angle and altitude variation, and reducing the severity of impacts during ramp loading and unloading. A leading taper intersecting a leading surface and air bearing surface of the slider is asymmetric about a longitudinal, bisecting plane of the slider. In another embodiment, side taper intersecting a side surface and air bearing surface of the slider is asymmetric about a latitudinal, bisecting plane of the slider. In another embodiment, rail taper intersecting a rail recess surface and air bearing surface of the slider is asymmetric about a longitudinal, rail-bisecting plane.
