A flow control device for a data storage system to reduce flow induced vibration. The flow control device includes a plurality of streamline flow passages to reduce turbulent flow in a flow field along a disc surface. Thus, air flow induced by rotation of data discs is directed through the plurality of streamline flow passages to reduce turbulence to limit excitation or vibration of the head and suspension components.

Drive level flow-field conditioning to reduce flow field turbulence

A shroud mounted to the housing of a disc drive blocks wind to the arm and suspension that positions a slider adjacent a recording surface of a disc. A first wall has a windward surface facing into the direction of rotation of the first disc. A second wall extends downwind from the windward surface between the arm and the disc to from a low-wind region with the first wall. The region is open at the leeward side so that the arm in the low-wind region positions the slider adjacent the disc. In some embodiments, a third wall is parallel to the second wall so that the low-wind region is a slot.
