Patent ID: 7561374

Claim:
A method of fabricating a disk drive comprising: selecting a weight plate to modify the vibration characteristics of a disk drive, the weight plate including a substantially flat outer surface and an opposing inner surface having non-extending edges, the disk drive including a printed circuit board assembly (PCBA) and a base having an exterior bottom side, a bottom peripheral edge disposed about the exterior bottom side, and an exterior facing cavity formed in the disk drive base adjacent the bottom peripheral edge and defined by the exterior bottom side; attaching the PCBA within a first portion of the exterior facing cavity of the base; and attaching the weight plate within a second portion of the exterior facing cavity of the base adjacent the PCBA such that the weight plate is located within the bottom peripheral edge and is substantially aligned with and substantially adjacent to the bottom peripheral edge, wherein the weight plate is selected based upon a mass of the weight plate in order to modify the vibration characteristics of the disk drive such that the disk drive is suitable for a pre-determined application.
