Abstract
- FEM-boundary integral method micromagnetic software was used to analyze the recording field response of an indented magnetic head to high frequency recording currents (1-4 GHz). Next, micromagnetic simulations of heat-assisted magnetic recording were performed and the signal-tonoise ratio (SNR) calculated at high frequencies. With a soft magnetic underlayer, the head field was large enough and gave higher SNRs. The large head field strength at low frequency did not cause any deterioration of the SNR.
