MAGNETO-OPTICAL RECORDING MEDIUM

摘要

Anticorrosion magneto-optical recording medium is disclosed. The magneto-optical recording medium comprises a recording layer (2) formed of an amorphous alloy of transition metal and rare-earth metal such as Tb-Fe or Tb-FeCo. On the recording layer (2), there are provided a transition metal layer (3) such as Fe CoCr alloy layer and a rare-earth metal layer (4) such as Tb, in this order. Selective oxidation of rare-earth metal in the recording layer (2) is effectively avoided by the existance of the layers.
