Abstract
Thermomagnetic recording process was simulated for Tbχ (Fe78Co22) 100-χ media with the thickness of 40 and 20nm by using Huth's model modified for the MFM recording.In the recording of marks smaller than-200nm, the recorded mark length was found to exhibit larger value than the designed mark. From the analysis of the effective fields acting on the domain wall, the stray field was found to be important factor in the recording of the small size marks.
