Abstract :
This article presents an approach to calculate magnetization behaviors of recording layer, soft under layer and write head in magnetic recording devices. Here, the macrospin calculation method is used with an increased Gilbert damping constant to compensate for the non-uniform magnetic states formed in fully discretized simulations.
