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.

A laser recording device of an embodiment is for a thermal recording medium in which at least one color development layer developing a color through heat and a protective layer protecting recorded information obtained through color development of the at least one color development layer are laminated, and has light transmission properties before recording. The laser recording device includes a recording head in which emitters emitting laser light from laser light sources are arranged, and a recording controller performing parallel processing of control for causing the laser light sources to emit light independently of each other and guiding the laser light from the emitters to the thermal recording medium.

A thermal medium and a laser recording device are provided in which medium parameters can be acquired efficiently. According to one embodiment, the thermal medium includes a photothermal conversion layer, a color development layer, a storage mechanism. The photothermal conversion layer converts an applied laser beam into heat. The color development layer develops a color by the heat converted by the photothermal conversion layer. The storage mechanism stores information related to a medium parameter including a photothermal conversion efficiency of the photothermal conversion layer.
