Abstract
The development of amorphous TbFeCo alloy films is summarized and from the dynamic read/write characteristics, TbFeCo films are confirmed to be very useful for digital memory applications. That is, the value of C/N is more than 50 dB and life times of more than 5 years were obtained even in the case of a PMMA substrate disk in ambient-air. From the study of oxidization resistance, it was confirmed that the long life time of this TbFeCo disk may be improved by adding some elements such as Pt, Ti, Al and Cr to TbFeCo. Some typical applications of this magneto-optical disk such as digital audio, digital still video file and digital data memory systems are also shown.
