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.

A disc head slider includes a slider body having a disc-opposing face with leading and trailing slider edges, a slider length measured between the leading and trailing slider edges, a bearing surface, a recessed area, an inlet and a convergent channel. The recessed area is recessed from the bearing surface. The inlet has a leading channel end, which is open to air flow from the leading slider edge, channel side walls and a trailing channel end. The convergent channel has a leading channel end, which is open to fluid flow from the inlet, channel side walls and a trailing channel end, which is closed to the fluid flow. The trailing channel end of the convergent channel is located along the slider length rearward of at least a portion of the recessed area and forward of at least a portion of the bearing surface.

A slider for supporting a transducing head proximate to a rotating disc. The slider has a slider body having a disc opposing face and a longitudinal axis. The disc opposing face is bounded by a leading edge, a trailing edge, and first and second side edges. An air bearing surface is defined on the disc opposing face with the air bearing surface having at least one pad located behind the leading edge. A cavity is positioned on the disc opposing face and the cavity is recessed from the air bearing surface at a cavity depth. At least a portion of the cavity precedes the pad. A funnel directs airflow within the cavity from the leading edge to the pad.

A disc head slider includes a slider body having a leading edge, a trailing edge, a slider length measured from the leading edge to the trailing edge, a central-recess floor and a plurality of raised rails. Each raised rail forms a respective bearing surface. At least one of the raised rails has a recessed rail surface, which is recessed from the respective bearing surface and raised from the central recess floor. At least twenty isolated bearing pads are positioned on the recessed rail surface and together form at least part of the respective bearing surface. Each bearing pad has a pad length and a pad width, which are at least one percent of the slider length.

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.

A head slider having a slider body with a disc facing surface and a bearing plane is provided. A first recessed area and a second recessed area are positioned on the disc facing surface and recessed from the bearing plane. A rail on the disc facing surface has a channel that includes a first side edge proximate the first recessed area and a second side edge proximate the second recessed area. The channel is isolated from the first recessed area and open to the second recessed area.

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.

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.
