International Classification:
G11B 560
US Classification:
3602366, 3602358
Abstract:
An air bearing slider designed for operation at ultra-low flying heights. The air bearing slider has an air bearing surface having portions which are constructed from a low-friction, high-wear-resistance material.

US Classification:
3602363, 3602356, 3602357
Abstract:
A disc head slider is provided, which includes a slider body having a disc-opposing face with leading and trailing slider edges and a slider length measured between the leading and trailing slider edges. The disc-opposing face has a bearing surface and a recessed area which is recessed from the bearing surface. A convergent channel is recessed within the bearing surface and has a leading channel end open to fluid flow from the recessed area, channel side walls, a trailing channel end closed to the fluid flow, and a channel length measured between the leading and trailing channel ends. The trailing channel end is located rearward of a midpoint along the slider length and the channel floor is vertically contoured relative to the bearing surface along at least a portion of the channel length.

US Classification:
2960312, 2960316, 3602354, 3602356, 3602369
Abstract:
A method is disclosed for constructing an ultra-low-flying-height slider for carrying a transducing head in a disc drive system including a rotatable disc. The method comprises removing material from an air bearing surface of the slider to create a channel at a likely location of contact with the rotatable disc and filling the channel with a low-friction, high-wear-resistance material. The channel is filled such that the air bearing surface is configured the same as the air bearing surface configuration prior to removing material.

International Classification:
G01B 1102
US Classification:
356507
Abstract:
A method and apparatus for performing interferometric measurement/testing of flying heights of read-write head sliders utilizing an improved rotating disk, the disk having a central opening for use with a spindle for rotation about a central axis, the disk comprising: a substrate comprised of a light transmissive material and including a pair of opposed, smooth, major surfaces; and a wear-resistant, protective overcoat layer on one of the major surfaces for improving the tribological properties thereof; wherein the optical properties of the one surface of the disk are optimized for enhancing the sensitivity of the interferometric measurement/testing by increasing the intensity of reflected light received by a detector of the apparatus.
