We proposed a new actuator that was composed by a layered piezoelectric element and a displacement amplitude mechanism. A new shape of the actuator which was like a diamond realized large working-distance with high resonance frequency. Moreover, as the two piezoelectric elements worked to counterbalance each other's reaction force, the new actuator never excite a spin-stand which was estimation tester for high density magnetic recording. We compared an original model with a newly improved one which was optimized by the integrated design method. The optimized design model increased the working-distance dramatically without its declining crossover frequency of the open-loop transfer function.
