  • Patent number: 8605389
    Abstract: There is provided a head gimbal assembly (HGA) for a disk drive. The HGA includes a slider and a flexure. The flexure includes a flexure body portion, a tongue portion with the slider affixed to the tongue portion, first and second gimbal arms extending between the flexure body portion and the tongue portion, and a dielectric layer including a first dielectric layer segment extending continuously along the first gimbal arm between the flexure body portion and the tongue portion. The flexure further includes a first patterned conductive trace electrically connected to the slider. The first patterned conductive trace is supported by the first dielectric layer segment. The first dielectric layer segment crosses and re-crosses the first patterned conductive trace along the first gimbal arm without overlying the first gimbal arm.

  • Patent number: 5750275
    Abstract: A magnetic thin film recording head includes laminated magnetic pole members, adjacent pole members being separated from each other by nonmagnetic insulating layers to reduce eddy current effects between the laminated members. The nonmagnetic insulating layers extend from the throat region of the head toward the pole tip region and terminate at a distance from the air bearing surface which is a function of the skin depth of the magnetic pole material for the particular recording frequency range being employed in the head.
