Abstract
The dual stage servo system is a technology corresponding to the high density of hard disk drives (HDDs). The suspensions for a dual stage servo system have PZT actuators on themselves. Because the PZT on a suspension is ceramic, the possibility of damage due to shock or impact is feasible. The fracture strength of PZT was evaluated by experiment and FEM analysis. Using that values and the results of Non-Operation shock examination and FEM simulation, we have found that a dual-stage actuator has enough shockproof property to withstand a 1000G level shock.
