The media magnetization, which was based on magnetic particle models, was introduced into the 3 dimensional finite element method using the commercial software JMAG-Studio. The head-medium interaction was accurately taken into account for the single pole head and double layer media perpendicular magnetic recording system. In order to deal with the medium movement, a regular mesh partition was realized. The effect of the single pole head structure on the recording resolution was investigated by using the newly developed program. It was found that a trailing-side return path structure in the down-track direction and a side-shield structure in the cross-track direction could significantly decrease the transition width and the track width, respectively.
