Abstract:
A thermal recording method comprising the steps of:recording a gradation image on a heat-sensitive recording material by scanning the heat-sensitive recording material in a main scanning direction with a laser beam modulated according to a gradation of an image to be recorded while conveying the heat-sensitive recording material in a sub-scanning direction relative to the laser beam, said heat-sensitive recording material which converts light energy applied thereto to heat energy and forms a color in a density according to the heat energy,wherein the heat-sensitive recording material comprises a support and a heat-sensitive layer which is substantially formed of organic material and which is formed on the support, andwherein a diameter d of the laser beam as measured in the sub-scanning direction, the recording intervals D in the sub-scanning direction and the sub-scanning frequency f are set to satisfy formulae:1.66.ltoreq.d/D.ltoreq.1.98+10.sup.4.25 .multidot.f.sup.-1.57 and200 Hz.ltoreq.f.ltoreq.900 Hz.
