초록

In this paper, perpendicular magnetic recording system which consists of a single pole head and a double, layer medium is analyzed by using 2D-finite element simulation and Preisach model for describing hysteresis characteristics. For confirming this method, we compare the calculated magnetic field intensity which is above the isolated transition of magnetization and scale up experimental data which have already published. The results show a good agreement and we can conclude that this method is very useful to analyze perpendicular magnetic recording system.
