ABSTRACT:
A displacement system for a hard disk drive comprising a driving circuit and first and second displacement elements. The driving circuit generates a driving signal from a source voltage level, a control signal, and a reference voltage level. The driving signal is applied across the first displacement element with respect to the reference voltage level. The driving signal is applied across the second displacement element with respect to the source voltage level.
