摘要： In a drawing method according to an embodiment of the present disclosure, when performing drawing on a thermal recording medium that includes, above a recording layer, a light-transmitting member having an uneven shape in a plane, an optical compensator having one surface and another surface is provided on the light-transmitting member to cause the one surface and the light-transmitting member to face each other, and the thermal recording medium is irradiated with a laser beam via the optical compensator. The one surface of the optical compensator has a shape that fits the uneven shape of the light-transmitting member, and the other surface is flat and opposed to the one surface.

摘要： 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.

摘要： 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.
