Abstract
A device comprises a fluid bearing including a textured fluid bearing surface and a second surface and a recordable disc. The recordable disc includes a substrate, a recordable media layer on the substrate, and at least one of the textured fluid bearing surface and the second surface. The device may be manufactured using MEMS techniques. MEMS techniques provide the high precision necessary to create the textured fluid bearing surface. MEMS techniques also allow the recordable disc to be batch-fabricated with one or more additional recordable discs.
