To improve the driving sensitivity of an optical pickup actuator for high density and high speed, we present a new magnetizing method-concentrated anisotropic magnetization for Nd-Fe-B sintered magnets. The electromagnetic field analysis applying 3-D FEM was performed and several samples were actually tested. From comparing simulated data with experimental results, we verified the accuracy of the simulation and the superiority of the presented method
