Abstract
A hard disk drive has a recirculation filter that shrouds the rims of disks at the inlet and outlet of the filter. The shroud is aerodynamically shaped to reduce flow-induced disk vibration of the read/write head. A significant improvement in non-repeatable run-out is provided when the inlet and outlet are shrouded along the rims of the disks.
