The apparatus comprises an airstream stripper downstream of the actuator with respect to the direction of air currents generated by the spinning discs. The airstream stripper comprises a vane extending substantially radially from an outer radial portion to an inner radial portion of the data storage disc and adjacent the data storage surface. The vane is disposed substantially transverse to the actuator distal end along the radial path of actuator travel across the data disc.

摘要： A disc drive includes a base, at least one disc rotatably attached to the base, and an actuator assembly rotatably attached to base and supporting a slider and a transducer at a distal end thereof. The slider and transducer are positioned to be in transducing relation with respect to the disc. An air dam is positioned over the disc and near an arc through which the slider and transducer are rotated. The air dam is positioned so as to produce an area of high pressure substantially about an area including a portion of the arc through which the slider and transducer are rotated. Surfaces are aligned with and extend in a coplanar relationship with the disc to transfer an outwardly directed airflow away from the disc without impinging turbulent flow on or at the disc edge.

摘要： Apparatus for providing nominally laminar flow of air currents in a disc drive. An actuator supports a head adjacent a rotatable disc and includes a rigid actuator arm with opposing planar top and bottom surfaces and a pair of opposing tapered surfaces which taper to a trailing edge. The top, bottom and tapered surfaces define a cross-sectional enclosure to provide nominally laminar flow of air currents adjacent the actuator arm induced by rotation of the disc. A channel is formed in the enclosure by a plurality of adjoining recessed surfaces to at least partially recess a head conductor along the length of the actuator arm within the enclosure to prevent obstruction of the air currents by the conductor. The conductor is preferably a flex circuit with a semi-flexible dielectric layer which supports a plurality of conductive traces.
