| Abstract | The hard disc drive is increasing the area density to meet the customer’s desire who want to keep the high definition of media and the huge data base for business or entertainment. Moreover, the wanted capacity of hard disc drive af fects the area density which must be involved by 60% to 100% per year. The track pitch i s dropped to a few nanometer and the servo bandwidth must be increased more than 5 kHz. A microelectromechanical system (MEMS) is developed to achieve the small stoke, as known as the PZT (Lead Zirconate Titanate) material; it provides the mechanical forc e and deformation when the voltage is applied and vice versa. This thesis presents the concept design of microact uator for 500kTPI hard disc drive. We study the couple field solid by using finite elemen t analysis to achieve the low power consumption of dual stage actuator design so that w e can reduce the power-gain circuit and the power consumption of hard disc drive. The microactu ator is designed to a type of piezoelectric microactuator having two piezoelectric elements whi ch are glued on the base-plate hinge. Finally, we come out with the optimized model of du al-stage actuator for 500kTPI hard disc drive. The design of experiment is used to understa nd the contributing factors and interactions that impact the power consumption of DSA model. The refore, the exact contribution is expressed to contribute the fabrication of DSA’s pr ototype in future. |
