Popis:	The elements of a vector Preisach model for unoriented thin-film media are described. The implementation consists of adding a biaxial anisotropy switching function to the classic Preisach algorithm. The model was developed to simulate high-squareness thin-film recording media. The utility of the model is demonstrated by the simulations of the usual VSM curves: the major loop, forward and reverse remanence loops, and the δM curve, as well as the response to rotating fields. These results are compared with experimental measurements made on an unoriented thin-film hard disk material.
