An optical information recording medium characterized by comprising a temperature-sensitive layer formed on a substrate, for reversibly changing in reflectance and/or transmittance with a temperature change. A temperature-sensitive layer having the property of changing in reflectance with a temperature change is used, as well as the property of changing in light interference effect with a temperature change, thereby providing an optical information recording medium capable of providing a higher, more stable reproduction signal power.
