Abstract:
In this work, we consider the application of an in-plane auxiliary field into the Exchange-Coupled Composite (ECC) medium in the Heat-Assisted Magnetic Recording (HAMR) system. The dynamic micromagnetic simulations are conducted based on the Landau-Lifshitz-Bloch (LLB) equations and the SNR characterizations are performed. The effect on the Signal-to-Noise Ratio (SNR) of the HAMR system is investigated. The improvement on the SNR with the auxiliary field in negative down-track direction is identified.
