Abstract:
An improved disk drive recirculation filter is provided. The filter comprises a fibrous layer disposed between two polymeric scrim or support layers. The scrim layers have a bond through their thickness, the bond forming a plurality of closed cells, such that the span on the unbonded area between the bonds is less than a critical fiber length dimension desired to be contained.
