ABSTRACT:
There is disclosed a method of successively forming and/or erasing images selectively in different portions of a recording layer of a recording medium which comprises a reversible thermosensitive recording material capable of recording images and erasing the same by reversibly changing the transparency or the color tone of the portions of the recording layer with the application of heat thereto, depending upon the temperature thereof, in such a manner that the same portion of the recording layer is not continuously used for image formation and/or erasure in excess of a predetermined number of times, thereby repeating the use of the recording medium for an extended period of time.
