Patent number: 5545477Abstract: Anticorrosion magneto-optical recording medium is disclosed. The magneto-optical recording medium comprises a recording layer formed of an amorphous alloy of transition metal and rare-earth metal such as Tb--Fe or Tb--FeCo. On the recording layer, there are provided a transition metal layer such as FeCoCr alloy layer and a rare-earth metal layer such as Tb, in this order. Selective oxidation of rare-earth metal in the recording layer is effectively avoided by the existance of the layers.Type: GrantFiled: February 25, 1991Date of Patent: August 13, 1996Assignee: Sony CorporationInventors: Nobuhiro Saito, Masaki Takenouchi
