Abstract
A disk drive includes a disk drive base and a latch attached to the disk drive base. The latch includes a latch impact surface having a latch impact surface perimeter. The latch impact surface perimeter defines a latch impact surface area. The disk drive includes a head stack assembly coupled to the disk drive base. The head stack assembly includes a tang. The head stack assembly is sized and configured to rotate to a parked position with the tang in mechanical communication with the latch. The tang has a tang impact surface. The disk drive includes a damping member disposed upon and disposed between the latch and the tang for damping impact between the tang and the latch and mitigating contact between the tang impact surface and the latch impact surface. The damping member has a damping member surface area less than the latch impact surface area.
