초록
In this paper, three dimensional Equivalent Magnetic Circuit Method(3-D EMCN method) a numerical analysis method which supplements to magnetic equivalent circuit adding numerical technique, is proposed for analysis Optical Pickup Actuator. (3) This method provides better characteristics both in precision of the analysis and in computation time than other analysis method such as three-dimensional Finite Element Method. We choose the simple 2-magnet moving coil type pickup actuator model and verify upper yoke effect using this method.
