Claims
- 1. A slider for maintaining a computer storage device transducer at a generally uniform flying height above a rotating storage medium as said slider is positioned with respect thereto, said slider including a generally elongate body portion having at least one major surface presenting at least two longitudinally positioned, generally parallel and spaced apart rails for extension towards said rotating storage media, wherein the improvement comprises:an air bearing surface formed on a distal surface portion of said rails, said air bearing surface occupying less than 50% of said distal surface portion of said rails; and at least one transverse pressurization contour adjoining said air bearing surface at said distal surface portion of said rails.
- 2. The slider of claim 1 wherein said rails further comprise a leading edge ramp at one end thereof for positioning in opposition towards a direction of rotation of said storage media.
- 3. The slider of claim 1 wherein said slider further comprises an ambient pressure slot between said rails.
- 4. A slider for controlling the flying height of a computer storage device transducer above a rotating storage medium, comprising:an elongated body having a medium facing major surface; a leading edge on the major surface; a trailing edge on the major surface; first and second generally parallel and spaced apart rails disposed on the major surface and extending substantially between the leading edge and the trailing edge; a first medium facing air bearing surface on the first rail; a second medium facing air bearing surface on the second rail; a first medium facing transverse pressurization contour surface and a second medium facing transverse pressurization contour surface longitudinally disposed on the first rail; a third medium facing transverse pressurization contour surface and a fourth medium facing transverse pressurization contour surface longitudinally disposed on the second rail; the first transverse pressurization contour surface being located laterally of the first air bearing surface; the second transverse pressurization contour surface being located medially of the first air bearing surface; the third transverse pressurization contour surface being located medially of the second air bearing surface; the fourth transverse pressurization contour surface being located laterally of the second air bearing surface; the first and second transverse pressurization contour surfaces occupying more than 50% of the first medium facing rail surface of the first rail; and the third and fourth transverse-pressurization contour surfaces occupying more than 50% of the second medium facing rail surface of the second rail.
