发明名称 Magneto-optical recording medium and reproducing device
摘要 A magneto-optical recording medium includes at least a first magnetic layer, a second magnetic layer and a third magnetic layer which are layered in this order, the first magnetic layer being formed of a perpendicularly magnetized film having a relatively small wall coercivity and a relatively large wall mobility compared with the third magnetic layer in the vicinity of a predetermined temperature, and the magneto-optical recording medium satisfies conditions<paragraph lvl="0"><in-line-formula>Tc2<Tcomp1<Tc1 and</in-line-formula><paragraph lvl="0"><in-line-formula>Tc2<Tcomp1<Tc3</in-line-formula>where Tcomp1 is a compensation temperature of the first magnetic layer, Tc1, Tc2 and Tc3 are Curie temperatures of the first, second and third magnetic layers, respectively.
