Recording medium and recording device

A recording device that performs recording on a recording medium, the recording device comprising a recording medium, said recording medium comprising:

• a base material;
• a first color development layer that is located on the base material and absorbs light of a given wavelength to develop color;
• a second color development layer that is located closer to an incident side of the given-wavelength light than the first color development layer, transmits visible light and the given-wavelength light, and develops a color by heat;
• a protective layer that is provided on the second color development layer;
• and
• a photothermal conversion layer that is located closer to an incident side of the light than the second color development layer intended to develop a color, transmits the visible light, and absorbs the given-wavelength light to photo-thermally convert the given-wavelength light into the heat, wherein
• the second color development layer comprises a plurality of second color development layers, and
• the photothermal conversion layer comprises a plurality of photothermal conversion layers corresponding to the plurality of second color development layers intended to develop respective colors, the plurality of photothermal conversion layers being arranged within the protective layer to be horizontally apart from each other;
• and
• wherein the recording medium further comprises:
• a light source that emits the light;
• an optical system that guides the light to a recording surface of the recording medium;
• an irradiation-position control unit that controls an irradiation position of the light;
• and
• an output control unit that controls, for color development of the second color development layer, an amount of heat generation from the photothermal conversion layer by controlling output of the light to be incident on the photothermal conversion layer.
