Abstract

The variable variance model is a Preisach-type model which has been shown to be applicable to artificial magnetooptic perpendicular recording media. In this paper, this model is extended to Co-Cr perpendicular media. It is found that, for this media the variance in the interaction field is larger in the saturated state than in the demagnetized state. More general functional dependencies on the magnetization are discussed.
