  • Patent number: 6606222
    Abstract: A disc head slider includes a slider body having a leading slider edge, a trailing slider edge and a slider length measured from the leading slider edge to the trailing slider edge. First and second raised rails are positioned on the slider body, which have first and second bearing surfaces, respectively. A recessed area is positioned between the first and second side rails and has a recess floor. A first raised pad is positioned rearward of a midpoint along the slider length and includes a third bearing surface, which is generally coplanar with the first and second bearing surfaces. A convergent channel is recessed within the third bearing surface and trails a portion of the recessed area. The convergent channel includes a leading channel end open to fluid flow from the portion of the recessed area, non-divergent channel side walls and a trailing channel end closed to the fluid flow and forward of a localized region of the third bearing surface.

  • Patent number: 6603639
    Abstract: A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system. For example, the pads may be used to reduce the stiction or improve flying characteristics. Flying instabilities associated with the pads are addressed by a number of characteristics provided to the air bearing surface.

  • Patent number: 6594113
    Abstract: A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a slider body having a disc opposing face bounded by a leading edge, a trailing edge and first and second side edges. The slider body has a longitudinal axis. An air bearing surface is defined on the disc opposing face. A furrow is positioned on the disc opposing face for flushing contaminants towards the trailing edge of the slider body.

  • Patent number: 6587308
    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.

  • Patent number: 6483667
    Abstract: A self-loading disc head-slider has a slider body, with a leading slider edge and a trailing slider edge, and first and second raised rails. Each raised rail has a leading rail edge, inside and outside rail edges and a bearing surface. A cavity dam extends between the first and second raised rails. A subambient pressure cavity trails the cavity dam, between the first and second raised rails. A stepped leading taper extends from the leading slider edge to the bearing surfaces of the first and second raised rails. The stepped leading taper is formed of first and second steps. The first step is positioned along the leading slider edge. The second step wraps around the leading rail edges of the first and second raised rails and extends along a portion of the inside and outside rail edges of the first and second raised rails. The first and second steps have a step height of 0.05 to 1.5 microns.
