Signal-to-noise ratio impact of grain-to-grain heating variation in heat assisted magnetic recording
Article 2014 EN
In this paper, we present a micromagnetic modeling study of the recording signal-to-noise performance of the heat assisted magnetic recording (HAMR) processes, focusing on the effect of possible grain-to-grain heating variation. The temperature variation is modeled by assuming a small random deviation of the steady state thermal profile for each grain. It is found that the temperature variation fr…
