Abstract

In this paper, we systematically perform optimal design of microwave-assisted magnetic recording (MAMR) and heat-assisted magnetic recording (HAMR) by applying response surface methodology (RSM) to optimize the signal-to-noise ratio (SNR) of the recording process. We evaluate the performance of design of MAMR and HAMR through micromagnetic modeling. Design of experiments (DoE) is conducted by using composite central design (CCD), and the influence of the design parameters on the SNR is investigated. The optimal designs of MAMR and HAMR systems are obtained by solving for the best-fit quadratic response-surface to the sampled points and solving for the parameters that maximize this cost function.
