Abstract
Comparative observations between heat-assisted magnetic recording (HAMR) experiments and micromagnetic modelling are presented and discussed in this work. Modeling results and experimental measurements show that the optimum HAMR recording is a tradeoff between two dominant noise mechanisms: erase-after-write and incomplete media saturation that are manifested as transition jitter and DC-media noise, respectively.
