An optical information recording medium capable of being drawn without being overturned by an optical information recording apparatus and cable of being drawn not depending on the wavelength of a laser light to be irradiated, the optical information recording medium having an information recording portion in which a recording layer and a first reflection layer are formed successively on a first substrate, and having a drawing portion in which a second reflection layer, a color-change layer, a color-change assistance layer, and a protection layer are formed successively on a second substrate, in which the second reflection layer is heated by irradiation of a laser light and the material in the color-change layer and the material in the color-change assistance layer are melted by the heat and mixed to cause a color change thereby forming images.
