Bi代石榴石磁光膜／金属反射层／玻璃多层结构磁光盘的优化设计

从磁光读出和热磁写入两者结合的角度提出一个新的优化目标函数．并用其完成了Ｂｉ代ＤｙＧａＩＧ／金属反射层／玻璃多层结构磁光盘的优化设计。结果表明新优化目标函数更具实际意义。

Optimization Design of Bi-substituted Garnet Film/Metal Reflective Layer/Glass Multilayered Magneto-optical Disks

Bi- substituted garnet films are most promsing of the next generation of themagneto-optical recording medium. In this paper we present the construction of a newoptimization objective function, which combines readout and thermal writing in a magnetooptical recording process. The method proposed is succeeded in the optimization design ofmagneto-optical disks, the structure of which is Bi-substituted DyGaIG/metal reflectivelayer (Al ) /Glass. The result shows that the new optimization objective function would havemore realistic significance.
