THE WIPING-OUT PROPERTY OF THE MOVING MODEL

This paper examines some properties of the moving Preisach model. It is found that this model can introduce hysteresis in materials where it is not intrinsically present. It is also shown that the moving model has the wiping-out property, even in the case where a reversible component of magnetization is present in addition to the irreversible component computed by the moving model. The implication of this model to the "over-write" problem in magnetic recording will be discussed.
