摘要：
The magnetic medium was included into the finite element method to analyze the recording mechanism of perpendicular magnetic recording. Interactions between the head and medium were accurately considered. The effects of media properties such as the anisotropy field dispersion, the easy axis distribution, and exchange coupling strength on the recording resolution were investigated using the developed program. It was found that reducing the dispersion of anisotropy fields was the most effective way to decrease both the transition width and track width. (c) 2005 American Institute of Physics.
