We have used a numerical model of thermomagnetic recording to investigate direct overwrite by domain destabilization in magneto-optical thin films. Our model includes a linear dependence of domain wall velocity on the net wall pressure due to the demagnetizing field and the wall energy density. Direct overwrite by domain destabilization can be accomplished in one step, without bias fields or prior reading or erasure.
