Top cover gasket to surround fastener opening to improve; torque retention, cover bowing, sealing, and acoustic performance. Presently, as the cover is torqued into place the cover gasket is only on one side, which causes an uneven torque distribution under the head of the fastener. The cover then tends to bow which can cause actuator pivot and/or spindle motor tilt when the perimeter fasteners are engaged; and the gap between the cover and respective shafts has increased. The acoustic performance is enhanced with the additional damping offered by the increased seal area. The resultant product yield and product performance/reliability will be improved.
