    摘要: An information handling system, such as a disc drive, including a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a load spring and a slider attached to said load spring. The slider has an air-bearing surface. The air-bearing surface includes a first rail, a second rail and a depression positioned between the first rail and the second rail of the air-bearing surface. The depression further includes a first level surface and a second level surface. The first level surface of the slider is at a different distance from a surface of the first rail of the slider than the second level surface of the slider. The air-bearing surface may also include a divider located between the first level surface of the slider and the second level surface of the slider.

    摘要: 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.

    摘要: A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a primary air bearing having a disc opposing face bounded by a leading edge and a first trailing edge. An air bearing surface is defined on the disc opposing face. The slider further includes a secondary air bearing having a disc opposing face bounded by a front edge and a second trailing edge. The air bearing surface is defined on the disc opposing face. The air bearing surface has a pad proximate the second trailing edge wherein the transducing head is located on the pad. An interface connects the secondary air bearing to the primary air bearing and the interface displaces the transducing head vertically with respect to the primary air bearing to maintain head media spacing (HMS) between the transducing head and the disc substantially constant as the slider flies above the disc.

    摘要: A disc drive includes a base, a disc stack rotatably attached to the base, and an actuator assembly. The actuator assembly also includes a load spring and an attached slider. The slider has an air-bearing surface that a leading edge, a trailing edge, and a center pad positioned near the trailing edge. A transducer is positioned within the center pad. The center pad has a channel cavity therein which is substantially parallel to the trailing edge. The channel cavity is positioned near or at the transition between the material making up the slider and an alumina portion. The channel cavity splits the center pad into a first center pad portion, and a second center pad portion. The width of the channel cavity is controlled to control the amount of movement between a substrate portion of the slider and a portion covering the trailing edge of the slider which results from annealing the slider.

    摘要: To allow for adjusting the fly height of a read/write head carried by a slider, a shear transducer is added to the slider. The shear transducer comprises a layer of piezoelectric material added to the slider so that the portion of the slider carrying the read/write head can be moved when the shear transducer is sheared. To cause the shear transducer to shear, a voltage is applied across the piezoelectric layer. To control the movement of the transducer, a closed-loop control system is used. The control system senses the spacing between the read/write head and the disc surface, compares the sensed spacing to a desired spacing, and adjusts the voltage applied to the shear transducer to reduce the difference between the actual and desired spacing.

Recessed leading channels are positioned near the leading slider edge and have a leading channel end open to fluid flow from the leading slider edge, non-divergent channel side walls, and a trailing channel end closed to the fluid flow. A trailing channel is recessed within each of the trailing bearing surfaces and has a leading channel end open to fluid flow from the respective recessed surface, non-divergent channel side walls, and a trailing channel end closed to the fluid flow.
