Abstract

Based on two simplified demagnetization criteria-critical load F c at the onset of plastic yield inception and Curie temperature T c in the magnetic recording medium, a two dimensional finite element model of a rigid cylinder lightly sliding over an elastic-perfectly plastic multilayered medium under coupled thermo-mechanical surface loading is developed in order to understand the thermo-mechanical behavior of the magnetic recording medium corresponding to demagnetization. Finally, some recommendations for anti-demagnetization are discussed.
