本文采用响应面法（RSM）系统地对微波辅助磁记录（MAMR）和热辅助磁记录（HAMR）进行优化设计，优化记录过程的信噪比（SNR）。我们通过微磁建模来评估MAMR和HAMR的设计性能。采用复合中心设计（CCD）进行了实验设计，研究了设计参数对信噪比的影响。通过求解采样点的最佳拟合二次响应面和使该代价函数最大化的参数，得到MAMR和HAMR系统的最优设计。
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.
