| 简介 |
Disclosed herein is a magneto-optical recording medium including a substrate, a first recording layer provided on the substrate, and a second recording layer provided on the first recording layer. The first recording layer contains Tb and FeCo as principal components and shows a compensation composition or transition metal dominance and perpendicular magnetization at room temperature. The second recording layer has a compensation temperature of not less than 100°C and shows rare-earth element dominance and perpendicular magnetization at room temperature. The Curie temperatures Tc1 and Tc2 of the first and second recording layers, the coercive forces Hc1 and Hc2 of the first and second recording layers at room temperature, and the thicknesses t1 and t2 of the first and second recording layers satisfy the relations of 60°C Hc2 · t2. |
