紙である。(Prior art) Conventionally, an ink ribbon made by forming an ink layer on one side of transparent base paper is irradiated with laser light, the ink layer absorbs the light and melts with heat, and this is transferred to plain paper for recording. There is a recording method to do this. Fig. 1 fd shows an outline of this type of recording method, where 1 is a laser light source, 21ri laser is an optical system that converges the Raded light emitted from the no light source 1, and 3 is a laser light source that converges the Raded light emitted from the light source 1. Deflection device to deflect, 7I is transparent base paper 5
This is an ink ribbon with an ink layer 6 formed on one side, and 7 sheets of plain paper.
偏向装置３を経たレーザ光がインクリボンに照射される

溶融して普通紙７に転写される。When the ink ribbon is irradiated with the laser light that has passed through the deflection device 3, the light is absorbed by the ink layer, and the ink in that area is heated and melted and transferred onto the plain paper 7.

るという欠点があっ／こ。By the way, this recording method requires a relatively large amount of optical energy to generate heat and melt the ink layer, and d) there is a limit to high-speed recording using a low-output laser. Another drawback is that the optical energy necessary for heat-generating melting differs depending on the constituent material of the ink layer, resulting in a lack of versatility for ink ribbons.
