摘要： A disk drive includes a disk drive base, a disk rotatably coupled to the disk drive base having a disk surface, a head stack assembly rotatably coupled to the disk drive base adjacent the disk surface, and a cover attached to the disk drive base enclosing the disk and head stack assembly there between. The cover includes a metal layer and a polymer layer substantially coextensive with the metal layer and extending substantially across the disk drive base. The polymer layer includes a polymer layer feature extending away from the metal layer towards the disk drive base. The polymer layer feature defines a cavity between the polymer layer and the metal layer.

摘要： A disk drive including a head disk assembly in communication with a printed circuit board assembly, and further includes a disk drive base and a disk drive cover assembly collectively housing a head stack assembly and a data storage disk mounted on a spindle motor assembly for rotating the storage disk. The disk drive cover assembly further includes first and second substantially-planar rigid members having major surfaces, a compressible member of a foam composition placed in between the major surfaces wherein the compressible member is characterized by an unconstrained thickness d1, and wherein the major surfaces and the compressible member are fixed in a stacked relationship to compress the compressible member to a thickness less than d1. The head disk assembly further includes structure for fixing the disk drive cover assembly to the head stack assembly and the spindle motor assembly.
