In recent years, a spin-stand system that is used to evaluate read-write performance of magnetic recording heads and media is required to compensate thermal drift and spindle-run out of the spin-stand self. We proposed Nano-motion Actuator (NMA) which consisted of a layered piezoelectric element (PZT) and a motion amplitude mechanism highly precise positioning with high speed. However, the NMA has very large amplitude in a resonance frequency. Since the resonance peak amplitude reduces servo bandwidth, we propose a damping mechanism for the NMA. As the mechanism damps resonance effectively, we can apply a FED controller for a model error that is caused by two different type attachments on the spin-stand system.
