Abstract
The present invention for a disk drive is a damping feature applied to the contact area between the flexible circuit and the pivot housing, reducing the resonance energy transferred from the flexible circuit to the pivot housing. This invention reduces the direct energy transfer from the flexible circuit to the pivot house by applying a damping feature as embodied by damping material on the flexible circuit or pivot housing at the point at which they make contact or by adding a damper to the flexible circuit re-routing tip area between the pivot housing and the flexible circuit. The damping feature absorbs the resonance energy from the flexible circuit to the damping feature material and reduces the energy transferred from the flexible circuit to the pivot housing.
