Summary:An apparatus is described which reduce flow-induced disturbances of the head. A disc drive assembly is provided which includes a basedeck and top cover. A spindle motor mounted to the basedeck which rotates around a central axis; at least one magnetic storage disc mounted to the spindle motor for rotation around the central axis and an actuator arm assembly. The actuator arm assembly includes an actuator arm rotatably attached to a pivot axis and a suspension arm attached to a distal end of the actuator arm. A magnetic transducing head is attached to the suspension. The head is used to read and write data to the magnetic storage disc. Finally, leading surface portion of the actuator arm utilizes several turbulence-reducing portions laterally recessed so as to guide an airflow to reduce a flow-induced disturbance acting on the transducing head.
