Abstract
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.
