    Abstract: YO986-013 MICRO MECHANICAL ACTUATED TRANSDUCER HEAD ON A SLIDER A micro-mechanical actuated transducer head on an air bearing slider is disclosed herein. The transducer head is made to move relative to the slider assembly by the incorporation of an actuating material intermediately to the slider assembly and head. The actuating material can be: electromechanical, piezoelectric, electrostrictive, thermal, pneumatic, or hydraulic. The actuating material can be incorporated either integral to the head/slider assembly or made to bridge the slider to head attachment. With the incorporation of said actuatable material, said head can be moved micro-mechanically relative to said slider effecting relative and controllable motion either horizontally and/or vertically.

    Abstract: An air bearing slider has both front and rear pads extending from a generally planar body, both pads having faces opposed to a recording medium and separated by a gap that is substantially in excess of any fly height of the slider. Both surfaces exhibit extremely small taper angles that enable "inlet throttling" of air beneath the slider. Such inlet throttling provides the slider with a fly height that is substantially independent of relative speed changes between the slider and a recording medium. A preferred embodiment includes front and rear pads that are convex in the direction of movement of the recording medium e.g. are "forward swept". Such convexity enables substantial resistance to fly height changes in response to skew alteration.
