There is provided an opto-magnetic recording medium having an exchange-coupled three-layered structure in which a recording layer having a high coercive force and a low Curie temperature at room temperature is sandwiched between read layers having a low coercive force and a high Curie temperature, wherein an iron group auxiliary lattice magnetization dominant rare-earth and iron group amorphous alloy thin film is adopted as the recording layer and the read layers, and directions of spontaneous magnetization of the three layers are parallel to each other.
