A magnetooptic recording medium capable of being resistant to cross talk and realizing a high-density recording enabling a small-pitch application. The magnetooptic recording medium comprises a magnetic 4-layer structure, a mask layer, a reproducing layer, an intermediate layer and a recording layer, characterized in that the reproducing layer and the recordimg layer have axes of easy magnetization in a laminate direction at room temperature, the mask layer and the intermediate layer have axes of easy magnetization in an in-plane direction at room temperature, relation, Tc 3 < Tc 2, Tc 3 < Tc 4 and Tc 3 < Tc 1, are satisfied when the curie temperatures of the mask layer, the reproducing layer, the intermediate layer and the recording layer are respectively Tc 1, Tc 2, Tc 3 and Tc 4, and the intermediate layer a rear earth-predominant magnetic layer.
