A highly precise tracking actuator for high magnetic recording density was developed. The tracking actuator was consisted of a displacement amplitude mechanism and a layered piezoelectric element (PZT). When the actuator was designed to increase its working distance, its resonance frequency was always reduced for a target value. The resonance frequency was not designed to independent the working distance. We applied a simultaneous optimal design method to the tracking actuator design. The crossover frequency of the open loop transfer function with the optimized actuator increased up to 23 % for the original one.
