ABSTRACT:
A voice coil for a voice coil motor of a hard disk drive comprises an inner surface of the voice coil, which bounds a central space of the voice coil. A first outer surface of the voice coil is substantially parallel to a second outer surface of the voice coil. A constrained layer damper is attached to the inner surface of the voice coil by a coupler. The constrained layer damper comprises a first constraining layer coupled to a first surface of a viscoelastic damping layer. A second constraining layer is coupled to a second surface of the viscoelastic damping layer. The constrained layer damper is curved in a direction that is substantially perpendicular to the first outer surface of the voice coil and the second outer surface of the voice coil.
