A filter assembly for a data storage device. The filter assembly includes a flow passage having an inlet and outlet to provide a recirculating filter. The filter assembly is positioned to provide a pressure differential between the inlet and outlet of the flow passage. A breather filter includes an opening for ambient air exchange through a second flow passage which is opened to the pressure differential of the flow passage of the recirculating filter to enhance ambient air exchange. An air dam assembly interposed in an air flow path provides a high pressure region and low pressure region. An assembly structure includes an air dam and a filter flow passage to enhance the pressure differential across the flow passage. Flow turbulence through the flow passage is reduced via flow plates supported between raised edge portions of the flow passage.

Filter assembly for a data storage device

A flow-induced disturbance upon an actuator arm is reduced. A gas flow generated by a rotation of a disc is received and passed along a surface. The surface is mechanically isolated from the actuator arm. The surface redirects the received flow to include a substantial inward radial component so as to be better aligned along a leading edge of the actuator arm.

Redirecting flow to reduce disturbances upon an actuator arm or head-gimbal assembly of a disc drive

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.
