Improvements to a self-consistent model for the magnetic recording properties of non-particulate media

Three aspects of self-consistent calculations are considered. The first includes various numerical techniques for reducing by a factor of 60 the running time of the original program. Second, a detailed treatment of the recording characteristics of the thin film head is given. Third, the model is expanded to two dimensions and used to compute with head motion the magnetization vector in a Fe3O4storage medium of moderate thickness. The role of this usually neglected out-of-plane magnetization component is discussed.
