ABSTRACT:
A thermal recording apparatus includes a laser beam generator for emitting a laser beam to record an image or the like on a thermosensitive recording medium, a preheating device for preheating the thermosensitive recording medium to a temperature lower than a coloring temperature thereof, an auxiliary scanning feeder for feeding the thermosensitive recording medium in an auxiliary scanning direction, and a controller for establishing a scanning interval employed when the image is to be recorded on the thermosensitive recording medium, depending on an amount of thermal deformation by which the thermosensitive recording medium is deformed when heated to the temperature lower than the coloring temperature. The thermal recording apparatus can record an image of desired dimensions on the thermosensitive recording medium without being adversely affected by shrinkage or expansion caused when the thermosensitive recording medium is heated before or after the image is recorded thereon.
