US 6,275,352 B1 · Individually tuned isolation devices for a disc drive base deck

Abstract

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.

Dependent claims

A disc drive, comprising:

a spindle motor which rotates a disc about a disc axis;
a base deck, having an interior surface and an exterior surface, the spindle motor mounted to the interior surface;
and
a plurality of isolation devices which receive fasteners to secure the base deck to a surface of a user environment in which the base deck is mountable, each of the isolation devices coupled to the exterior surface of the base deck and comprising:
a rigid threaded collar into which a corresponding one of the fasteners is engagingly inserted;
a compliant elastomer portion which mechanically isolates the collar from the base deck so that neither the collar or the corresponding one of the fasteners contacts the base deck, each elastomer portion secured within a corresponding recess of the exterior surface of the base deck;
and
a rigid stiffener which surrounds at least a part of an outer surface of the elastomer portion to form an aperture between the stiffener and the base deck.
