ABSTRACT:
A magneto-optical disk memory comprises a magneto-optical recording medium constituted by a flexible substrate, and a recording thin film overlaid on the substrate. The recording thin film is fabricated of an amorphous rare-earth transition metal alloy having the easy axis of magnetization normal to the film surface. The magneto-optical recording medium is sandwiched between two hard supporting disks.
