The main attention has been paid on amorphous rare earth- transition metal alloy films for magneto-optical storage and amorphous semiconductor films for phase change optical storage.

我们主要注意磁光型存储的非晶态稀土-过渡金属合金薄膜和相变型光存储的非晶态半导体薄膜两个方面。

So the conventional magneto-optical recording median, rare earth-transition metal (Re-Tm) alloys, is limited, because of its small Kerr rotation in the region of short wavelength.

因此传统的磁光记录介质-稀土金属与过渡组金属的合金就表现出局限性，因为这种材料在短波长范围的磁光效应很小。
