Abstract

Magneto-optical (MO) disk is a new memory which has merits of optical memory and magnetic memory. The merits are “high density recording of 108bit/cm2”, “disk-changeability and portability”, and “limitless rewritability”. The recording films of the disk, however, have the drawback of poor corrosion resistance and the achievement of sufficient disk-reliability is an important matter for the practical application. The corrosion of the recording films has been successfully prevented by coating protective layers and by improving corrosion resistance of the films themselves. Now the MO disk grows to have sufficient reliability and recording properties.
