Individually tuned isolation devices for a disc drive base deck

摘要

An apparatus and method for minimizing the effects of rotational and translational vibrations on a disc drive. A plurality of isolation devices are integrated into a base deck of the disc drive at industry standard locations. Each isolation device includes a rigid threaded collar into which a corresponding fastener is inserted to secure the base to a user environment, a compliant elastomer portion disposed between the collar and remaining portions of the base deck and a rigid stiffener which contacts and surrounds at least a portion of an outer surface of the elastomer portion. Stiffnesses of the elastomer portions are individually selected so that the plurality of isolation devices cooperate to reduce the effects of various translational and rotational vibratory inputs by bunching resonance modes within a selected frequency range.
