Abstract
As areal recording density and read/write frequency have been increasing rapidly, mechanical structure to clamp head gimbals assembly (HGA) at the top of a magnetic recording test stand is required for the multi-degree-of-freedom alignment to correspond to various HGA and for achieving higher head-positioning servo performance by increasing servo bandwidth by additional actuator. A new mechanical structure of additional actuator with PZT as displacement expander has been proposed. This paper discusses the integrated design of the mechanical structure and active controller for the proposed actuator. The robust performance is examined with the uncontrollable modes in relation to the structure perturbations.
