Patent number: 5726831Abstract: The invention provides a magnetic head slider with flying height that is uniform over a recording surface and is relatively insensitive to altitude changes when used in a data storage device. In one embodiment, a slider platform carries two or more gas bearing pads in the form of TPC type pads, each having a transverse pressurization contour along at least one side edge of its face, at least one NP type pad provided with a bearing face and a recess which develops a subambient pressure level, and an ambient pressure reservoir separating each TPC type pad from each NP type pad for preventing hydrodynamic interaction between the pads. The ambient pressure reservoir defines a cavity having a depth with respect to the face of each TPC pad sufficient to maintain substantially ambient pressure in the cavity during movement of the recording medium. In another embodiment, the gas bearing pads take the form of a combination of pads with transverse pressurization contours and pads without TPC effects.Type: GrantFiled: June 6, 1996Date of Patent: March 10, 1998Inventor: James W.

Patent number: 5159580Abstract: A uniquely designed acoustic transducer comprising a stack of piezoceramic elements (other piezoelectric materials may be used) mounted upon a tuned, shaped transmit/receive head made of hardened metal alloy. The ceramic stack is preloaded to the head via a stress bolt. Insulator electrodes used in the ceramic stack are selected to minimize compliance in the stack for maximum efficiency. All the material properties, sizes, weights, etc., as well as the overall transducer design are carefully selected to act in combination to match the impedance of the load (i.e. metal structural framework). The diameter of the tip of the tuned, shaped driving head is sized such that when clamped to a metal framework, the base metal of the material just under the tip is compressed to or slightly beyond its yield point. This eliminates the requirement for surface preparation because any coatings will be displaced under the applied pressure and any surface irregularities will be flattened out.Type: GrantFiled: October 3, 1991Date of Patent: October 27, 1992Assignee: Ocean Systems Research, Inc.Inventors: James K. Andersen, John H. Thompson, James W. White

Patent number: 5022470Abstract: An autonomous ice penetrator/payload delivery system is provided which, when once launched from its parent vehicle will, upon reaching the surface of the ice automatically right itself to proper orientation with respect to the ice surface for penetration. A modified solid propellant rocket engine is used as the heat source to penetrate the ice rapidly and automatically is ignited upon the ice pentrator/payload containment vessel attaining proper orientation with its longitudinal axis substantially normal to the ice surface. The hot gasses of combustion produced by the modified rocket engine impinge upon the ice thereby melting it. As the ice is melted and penetrated, the penetrator/payload containment vessel will follow the receding ice surface either by gravity, or by motive forces provided by the modified rocket engine, or both.Type: GrantFiled: June 28, 1989Date of Patent: June 11, 1991Assignee: Ocean Systems Research, Inc.Inventors: James K.

Patent number: 4870519Abstract: A slider assembly for flying a magnetic head at very low clearances on a fluid film over a moving recording medium. This improved slider assembly provides stability and uniformity of flying height and increased damping characteristics when the slider assembly is subjected to dynamic forces. The slider assembly has, in most embodiments, a pair of rails each having a tapered forward end to provide a converging inlet to achieve the fluid film. Most of the static load is carried by the flat surface of the rails rearward from that tapered forward end. Each rail of the slider assembly has at least one longitudinal transverse pressurization contour (TPC) along corresponding edges of the rails to provide this stability of flying height. When only one TPC per rail is used, the particular edge chosen for the TPC depends upon the disk size and skew angle distribution over the recording zone. The TPC's can be of step construction, a linear taper or a convex configuration.Type: GrantFiled: November 20, 1987Date of Patent: September 26, 1989Inventor: James W. White

Patent number: 4673996Abstract: A slider head assembly for flying a magnetic head at very low clearances on a fluid film over a moving recording media. This improved slider head assembly has at least one air bearing surface that flies above the recording medium due to pressurization of air under that bearing surface as the recording medium is rotated. The air bearing surface is provided with a transverse pressurization contour (TPC) along each side edge of the bearing surface such that any air flow from the side of the slider assembly, due to skew angle operation and/or access velocity, produces pressurization adjacent to one side edge and expansion adjacent to the other side edge of each air bearing surface. The pressure distribution across each air bearing surface is substantially symmetrical from side to side. This construction makes the slider assembly flying height and roll angle essentially insensitive to skew angle and/or access velocity. One of the embodiments utilizes a TPC having a linear taper of generally less than one degree.Type: GrantFiled: April 29, 1985Date of Patent: June 16, 1987Inventor: James W. White
