| Abstract: | We discussed the temperature distribution in the
tiny zone irradiated by laser beam in single layer film and multi layered film during magneto
optical static recording process, and educed the resolution expression of the temperature
variation in multi layered film under the irradiation of the laser beam. The field of
instantaneous temperature was simulated, the size of written domains of TbFeCo material
was calculated, and the domain shape was also estimated. The simulation was very useful for
widening the temperature and analyzing the temperature characteristic or shape of the surface
of magnetor optical film. |

| Keywords: | magneto optical recording written domain laser pulse finite differentiate method field of instantaneous temperature |
