US Patent 8929032 Baseplate resonant axis optimization

In one implementation, the presently disclosed technology teaches an apparatus with a head attached to an end of a baseplate. The baseplate includes a tilted section that causes a torsion axis of the baseplate to pass near the head. In another implementation, the presently disclosed technology teaches an apparatus with a load beam attached to a baseplate. The apparatus also includes a head attached to an opposite end of the load beam from the baseplate. The baseplate includes a mass-shifted section that causes a torsion axis of the apparatus to pass through the head. In yet another implementation, the presently disclosed technology teaches a method for reducing baseplate resonance amplitude. The method includes shifting a baseplate mass on a suspension toward an adjacent disc surface to move a baseplate torsion axis to pass near a head.
