摘要：

To take the interparticle magnetic interaction into account, the mean field theory was introduced into our magnetic recording simulator based on a finite element method and the curling magnetization switching model. Remanence curves and Henkel plots were well stimulated by computer for Ba-ferrite media which exhibit the large positive interparticle interaction. The perpendicular magnetic recording performance is strongly influenced by the interparticle interaction. A larger reproduced voltage is obtained when the interaction is stronger.
