Thermal recording device with controller for correcting laser beam intensity

A thermal recording device for scanning a laser beam over a thermosensitive recording medium which comprises a support coated with a coloring agent, a color developer, and a light absorbing dye and produce a color having a density commensurate with the level of a thermal energy applied thereto, thereby to record an image thereon, said thermal recording device comprising:

• a laser beam applying mechanism for emitting and applying a laser beam modulated by an image signal to be recorded to the thermosensitive recording medium;
• a heating mechanism for preheating the thermosensitive recording medium, before the laser beam is applied thereto, up to a predetermined temperature lower than a temperature at which the thermosensitive recording medium produces a color;
• a temperature detecting mechanism for detecting a temperature with respect to the thermosensitive recording medium;
• a humidity detecting mechanism for detecting a humidity with respect to the thermosensitive recording medium;
• a controller for correcting the intensity of the laser beam emitted by said laser beam applying mechanism and/or the predetermined temperature produced by the heating mechanism based on the temperature detected by said temperature detecting mechanism and the humidity detected by said humidity detecting mechanism.
