ABSTRACT:
A recording and erasure of a visible image on a reversible heat-sensitive recording medium can be repeatedly performed in a stable condition without failure. The visible image is recorded by a thermal recording head on the reversible heat-sensitive recording medium. The recording medium is provided with an unheated area which is not exposed to heat. The visible image is erased by providing heat by a thermal erasing head. The reversible heat-sensitive recording medium is provided with an unheated area which is unheated by the thermal erasing head. The unheated area substantially extends along at least one of sides of the reversible heat-sensitive recording medium. The unheated area prevents the reversible heat-sensitive recording medium from being warped when a erasing operation is repeated many times.
