Title:
HEAT SENSITIVE MEDIUM AND LASER RECORDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/193757
Kind Code:
A1
Abstract:
Provided are a heat sensitive medium and a laser recording device capable of efficiently acquiring a medium parameter. According to an embodiment, the heat sensitive medium is provided with a photothermal conversion layer, a color developing layer, and a storage mechanism. The photothermal conversion layer converts an irradiated laser into heat. The color developing layer develops a color with the heat converted by the photothermal conversion layer. The storage mechanism stores information relating to a medium parameter including photothermal conversion efficiency of the photothermal conversion layer.
