Disc drive protective cover to improve shock robustness

摘要

A shock protection assembly for a disc drive includes a protective cover mounted as the lowest portion of the disc drive. The disc drive includes a base plate and two mounting rails, wherein a printed circuit board assembly is attached to the base plate between the two mounting rails. The protective cover is mounted to the base plate to cover a majority of the printed circuit board assembly while extending a predetermined distance below the mounting rails to shield the mounting rails and the base plate from contact. The shock protection assembly may further include a shock damper positioned between the protective cover and the printed circuit board assembly.
