Abstract

In this paper, perpendicular magnetic recording system which consists of a single pole head and a double layer medium has been analyzed by using 2D-finite element method and preisach model for describing hysteresis characteristics. To verify the validity of this method, we compare the calculated magnetic field intensity which is above the isolated transition of magnetization with scaled up experimental data published in reference [7]. The results show good agreements within 7% error bounds and it is therefore concluded that this method will be very useful to analyze perpendicularmagnetic recording system with hysteresis characteristics.
