摘　　要：利用有限单元法研究了环境温度、写入光功率、磁光盘膜面温度分布三者间的关系，在此基础上导出了宽温环境下的最优写入条件，该条件为优化宽温磁光盘读出性能提供了依据。With a finite--element method, the relationships among ambient temperature and writing power, as well as the temperature distribution in the mangeto-optical(MO) film are discussed. On the basis of a numerical analysis, the optimum recording condition adapted for different ambient temperatures is derived. Also,the analysis presents an access for optimizing the readout characteristics of MO disks at different ambient temperatures.
