A magnetooptical recording medium has at least two recording layers (3,4) formed on a substrate (1) and having mutually different Curie temperature. The recording layer (3) having the highest Curie temperature is formed with a thickness greater than 0.5 nm but not exceeding 5 nm. The recording medium having at least two recording layers, includes an exchange-coupled multi-layered film of rare earth-iron group alloys consisting of a first recording layer of a high Curie temperature and a small vertical magnetic anisotropy, and a second recording layer (4) of a Curie temperature lower than that of the first recording layer and a vertical magnetic anisotropy larger than that of the first recording layer. <IMAGE> |
