Thermal bit writing simulations in magneto-optic recording media

A micromagnetic simulation based on the Landau-Lifshitz-Gilbert equation in cludes random field terms to represent thermal effects. By recalculating th e temperature of each cell in the simulation at each time step the effects of localised heating by a laser and of heat conduction can be included in t he calculations. This allows a simulation of magneto-optic recording proces ses to be carried out. Single bit nucleation in zero field was simulated, a s were written tracks.
