A disc drive has an actuator assembly that includes an actuator arm and a suspension having a load beam for supporting a head above a surface of a disc. The actuator assembly includes a plurality of surface features formed on a surface of at least one of the actuator arm and the load beam to reduce aerodynamic drag forces experienced by the actuator assembly. The disc drive may also include an air dam having a finger extending over the surface of the disc, where the finger includes a plurality of surface features to reduce flow separation of an airflow passing over the finger. The surface features may comprise dimples or V-shaped shark skin denticles.

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 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.

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.

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 âflyâ 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.

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.

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.

Herein is disclosed a method and apparatus for reducing particle collection on a slider or gimbal tongue. The gimbal tongue is shaped so as to interact with airflow within a disc drive to direct particles away from the slider and gimbal tongue. The leading edge of the gimbal tongue overhangs the leading edge of the slider. As air current approaches such a geometry, a large pocket of slow moving, high pressure air is created just upwind of the slider. Thus, as particulate matter encounters this pocket, the matter is slowed and its momentum is partially dissipated. A vent is provided in the gimbal tongue. The vent permits an escape route for the particles to move to an area of lower pressure, located on the other side of the gimbal tongue.
