    摘要： An aerodynamic slider has at least one side surface that is continuously curved between the leading and trailing surfaces to substantially eliminate off-track forces on the side surface due to changing skew orientations. A slider profile is modeled, and a numerical simulation of airflow on the modeled profile is generated for each of a plurality of skew orientations within a range of skew orientations at which the slider will fly. The modeled slider profile is repeatedly adjusted based on the numerical simulations until a vibration analysis on the modeled profile indicates vibration does not exceed a predetermined minimum.

    摘要： An air bearing for a slider including cooperating raised bearing surfaces or portions along a trailing edge portion of the slider. The cooperating raised bearing surfaces or portions are formed on a stepped bearing surface which is elevated above a recessed bearing surface. The cooperating raised bearing surfaces or portions form raised rails or rails portions or a raised center pad or raised center pad portion on the stepped bearing surface to reduce cross curve sensitivity.

    摘要： A slider for supporting a transducing head proximate to a rotating disc. The slider has a slider body having a disc opposing face and a longitudinal axis. The disc opposing face is bounded by a leading edge, a trailing edge, and first and second side edges. An air bearing surface is defined on the disc opposing face with the air bearing surface having at least one pad located behind the leading edge. A cavity is positioned on the disc opposing face and the cavity is recessed from the air bearing surface at a cavity depth. At least a portion of the cavity precedes the pad. A funnel directs airflow within the cavity from the leading edge to the pad.

    摘要： An air bearing slider including a recessed cavity surface to provide an adaptable bearing surface to compensate for thermal expansion or pole tip protrusion. The recessed cavity surface forms a leading edge cavity step to a raised bearing surface proximate to a trailing edge of the slider. The leading edge cavity step forms a rampless air bearing surface proximate to the trailing edge of the slider which is adaptable to form a ramp to pressurize a protruding surface of a transducer portion of the head.

    摘要： One embodiment of the present invention pertains to a slider that includes an aerodynamic surface which includes a first bearing surface, a cavity floor, and a first recessed pressurization surface. The first bearing surface is disposed on the aerodynamic surface, defining a bearing height. The cavity floor is disposed on the aerodynamic surface at a cavity depth below the bearing height. The first recessed pressurization surface is adapted to provide above-ambient fluid pressure when the slider is in nominal flight, which is greater than fluid pressure provided elsewhere on a trailing half of the aerodynamic surface at a substantial displacement from a longitudinal centerline of the aerodynamic surface. The first recessed pressurization surface is disposed on the aerodynamic surface at a recessed depth which is between the bearing height and the cavity depth.
