A reversible multicolor thermal recording medium which is free from fogging and has sharp contrast even after recording and erasing are performed repeatedly, and a recording method using the same are provided.A reversible multicolor recording medium is provided, which includes recording layers each containing a plurality of reversible thermal coloring compositions having different coloring tones, formed to be separated from and stacked on a surface direction of a supporting substrate; and the plurality of reversible thermal coloring compositions containing light-to-heat transforming materials which absorb infrared rays having different wavelength ranges to generate heat, respectively; wherein an absorption peak wavelength of the light-to-heat transforming material contained in the recording layers becomes the longest wavelength at the layer formed nearest the supporting substrate, and becomes a shorter wavelength as the layer is closer to the surface layer in the stacked order.
