摘要：

Thermomagnetic recording process was simulated for Th-X(Fe78Co22)(100-X) media by using Huth's model modified to apply the magnetic field modulation (MFM) recording method. In the case of X = 17.6 (TM-rich) medium recorded with I mum laser spot and single pulse field, the recorded mark length becomes much longer than designed one when it becomes shorter than 100 rim. In the case of X = 21.7 (RE-rich) medium, the recorded mark lengths is not so much longer compared to those of X = 17.6 and 19.4, but it becomes difficult to record marks shorter than 40 nm due to the collapse of domains. The influence of magnetic parameters on the recording characteristics is also discussed.
