Abstract

In this paper, slim type optical pickup actuator was fabricated and its FE model was tuned to experimental results through precise coil models. In order to widen its control bandwidth, stiffness of moving parts was increased by changing shape of coil section. Finally, we checked that flexible mode frequency and gain margin was increased.
