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

摘要

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.
