The present invention provides a reversible multicolor thermosensitive recording medium having clear color development / contrast and contrast and capable of repeated recording and erasing, and a recording method using the same. In a reversible multicolor recording medium having a configuration in which recording layers (11-13) are laminated in the surface direction of a support substrate (1), the recording layers (11-13) absorb infrared rays in different wavelength ranges. A heat-generating light-to-heat conversion material, a color developing compound, a developer / subtractor, and a sensitizer are included, and the chemical structure of the developer / subtractor and sensitizer is specified and excellent. Realize high color-decoloring characteristics, contrast, and fineness to improve recording sensitivity. [Selection] Figure 1 |
