Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical information recording medium capable of easily determining the proper execution of the heat treatment thereof, and a method and a device for determining heat treatment. SOLUTION: The magneto-optical information recording medium is provided with a magnetic layer constituted of a recording layer, a moving layer and a cut-off layer, and a reflectance changing film arranged on a side opposite the cut-off layer to hold the recording layer therebetween. In the device for determining heat treatment, a change in the reflectance of the reflectance changing film is used. After the heat treatment is executed by a laser beam from an LD21, the laser beam of power smaller than that of the laser power is applied from the LD21 to a magneto-optical disk 38, and its reflected light quantity is detected by a photodetector 31. A controller 33 determines whether the reflected light quantity is within a permissible range or not. If it is outside the range, the power of the laser beam for the heat treatment is adjusted, the treatment of the magneto-optical disk is canceled, or the message of that effect is displayed and so on.
