摘要：

A micromagnetic model for studying recording and noise characteristics in perpendicular media with a soft magnetic underlayer has been developed. The single pole head and soft magnetic underlayer are modeled with two-dimensional meshes and the medium is modeled with a three-dimensional granular structure. Utilizing the model, the dependence of recording characteristics on a medium microstructure, especially the intergranular exchange coupling, and write field is investigated.
