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.

Thermal medium and laser recording device

A recording medium according to an embodiment includes a base material; a first color developing layer that is laminated on the base material, and absorbs light having a given wavelength to develop a color; a photothermal conversion layer that is laminated closer to an incident side of the light than the first color developing layer, transmits visible light, and absorbs the light for photothermal conversion; and a second color developing layer that is laminated closer to the incident side of the light than the first color developing layer, transmits visible light and the light, and develops a color by heat converted by the photothermal conversion layer.
