Abstract: An erasing unit according to an embodiment of the present disclosure is a unit that performs erasing of information written on a reversible recording medium. This erasing unit includes: a light source section including one or a plurality of laser devices; and a controller that controls the light source section to cause the light source section to emit a smaller number of laser light beams having emission wavelengths than the number of the recording layers included in the reversible recording medium.

Abstract: A drawing system according to an embodiment of the present disclosure includes a storage, an operation section, and a drawing section. The storage stores a characteristic function that derives output setting values of light sources on the basis of drawing coordinates, an absorbance correlation value, and gradation values in a leuco color space. The operation section derives the output setting values by inputting, to the characteristic function, the drawing coordinates, gradation values of leuco image data described in the leuco color space, and an absorbance correlation value obtained by measuring the recording medium. The drawing section includes the light sources, and controls output of the light sources on the basis of the output setting values derived by the operation section to thereby perform drawing on the recording medium.

Abstract: A reversible recording medium according to an embodiment of the present disclosure is a reversible recording medium that includes recording layers and heat-insulating layers that are alternately stacked, in which the recording layers each include a reversible heat-sensitive color developing composition and a first light-heat converting agent. In this reversible recording medium, the recording layers are different from each other in a developing color of their respective reversible heat-sensitive color developing compositions and are different from each other in an absorption wavelength of their respective first light-heat converting agents. This reversible recording medium further includes a heat-generating layer that includes a second light-heat converting agent having an absorption wavelength that is different from the absorption wavelength of the first light-heat converting agent included in each of the recording layers.

Abstract: A drawing system according to an embodiment of the present disclosure includes a storage, a generator, and a drawing section. The storage stores a conversion table that describes a correspondence relationship between gradation values in a leuco color space and output setting values of light sources. The generator generates, on the basis of leuco image data described in the leuco color space and the conversion table, the output setting values corresponding to the leuco image data. The drawing section performs drawing on a recording medium on the basis of the output setting values generated by the generator, the recording medium including a plurality of recording layers, the plurality of recording layers each including a leuco dye and a photothermal conversion agent.
