Abstract
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 d, 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 d. The head disk assembly further includes structure for fixing the disk drive cover assembly to the head stack assembly and the spindle motor assembly.
