摘要： A slider includes a slider body having a leading edge, a trailing edge, a first side edge, a second side edge and a center line extending between the leading edge and the trailing edge, which define a disc-facing surface having a bearing plane. A protrusion is positioned on the disc-facing surface along the first side edge and has a protrusion surface. The protrusion surface is tilted with respect to the bearing plane about the center line and towards the first side edge.

摘要： A disc drive assembly includes a housing, a disc, an actuator, a ramp and a slider. The ramp is positioned along an edge of the disc to engage a portion of the actuator when the actuator is in a parked position. The slider is supported over the disc by the actuator and includes first and second elongated rails. Each rail has a leading bearing surface, a trailing bearing surface, and a recessed area extending between the leading and trailing bearing surfaces. First and second convergent channels are recessed within the trailing bearing surfaces of the first and second rails, respectively. Each channel includes a leading channel end open to fluid flow from the respective 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 respective trailing bearing surface.

摘要： According to one embodiment of the present invention, a fly height of a read/write head in a disc drive is actively controlled as the read/write head is positioned over a rotating disc with a patterned media. The patterned media includes ridges and grooves in servo wedges in the patterned media. According to another embodiment of the present invention, an estimated fly height of the read/write head is compared with a desired fly height to generate a control signal. The control signal is used to apply a voltage difference across a piezoelectric layer joining the read/write head to a slider to move the read/write head relative to the slider and adjust the fly height of the read/write head. According to another embodiment of the present invention, a map of ridges and grooves in the patterned media is generated and the fly height of the read/write head is actively controlled based on information in the map.

摘要： A disc head slider for supporting a transducer relative to a data storage disc includes a slider body having a disc-facing surface with a leading slider edge and a trailing slider edge. First and second rails are disposed on the disc-facing surface about a central recess and form first and second bearing surfaces, respectively, which terminate prior to the trailing slider edge. First and second wear-resistant pads are formed on the disc-facing surface between respective ones of the first and second bearing surfaces and the trailing slider edge. The first and second wear-resistant pads are raised from the central recess and are recessed from the first and second bearing surfaces to provide transitions in the disc-facing surface that generate vibration-dampening pressure gradients while limiting contact between the pads and the data storage disc during operation.
