Magnetization switching in energy assisted recording is examined using micromagnetic simulations. Heat assisted and microwave assisted recording are compared. The high frequency magnetic field used in microwave assisted recording can be used to reduce the switching field or the switching time, but the optimum frequencies have opposite trends as a function of temperature. In heat assisted recording the switching times at temperatures near to the Curie temperature are about half the room temperature value. In recording simulations heat assisted recording was able to write the highest quality tracks and has the potential to be able to write on media with much higher anisotropy than microwave assisted recording.
