Abstract
An apparatus which provides improved fluidic control includes a circumferentially extending windage plate adapted for placement adjacent a rotatable disc surface. The plate operates to direct fluidic currents established by rotation of the surface. One or more snubber members are supported by the plate to prevent localized contact between the plate and the surface as a result of deflection induced by application of a mechanical shock. Preferably, an access element is moveable along a movement path adjacent the rotatable surface. An air dam comprising a localized increased thickness portion of the plate at a leading or trailing edge of the plate preferably further directs the fluidic flow, and the snubber member-further prevents contact between the air dam and the rotatable surface. The rotatable surface preferably comprises a data recording surface and the access element preferably comprises a data transducing head.
