Abstract
A reversible thermal recording medium having a core material capable of being change in state by heat and a recording layer including capsules containing this core material. A repeatability corresponding to the limit of possible repeated recording/erasing effected by a physical or chemical change in the material constituting the recording can be obtained. A deterioration in image quality caused by transfer of a part of the recording layer to the heating unit can be prevented and repeat characteristics can be improved, thereby limiting the running cost.
