ABSTRACT:
A disk drive includes a spindle motor, a pivot bearing cartridge, and a laminated cover. The laminated cover includes a first cover layer attached to the spindle motor, and a second cover layer attached to the pivot bearing cartridge. The cover further includes a damping layer disposed between the first and second cover layers for mechanically insulating the spindle motor and the pivot bearing cartridge from each other to mitigate vibration through the cover.
