Abstract

This invention is a method to solve the resonance problem by re-arranging dummyheads of de-pop actuator of HDDs. So far, dummyheads are designed just for balancing the de-pop actuator and adjusting the inertia. The transfer function of dummyhead itself is different from that of HGA, so high frequency resonance of de-pop actuator and full head actuator become different. Sometimes it causes
