Abstract
An actuator for a direct access storage device has a secondary actuator with discrete or distributed masses such that a mechanical nodal point is created. The nodal point does not move with respect to the primary actuator. The secondary actuator is attached to the primary actuator at a nodal point. No net forces are coupled to the primary actuator when the secondary actuator is activated in a vibratory movement by a piezo-electric element.
