Method and apparatus for the enrolment again and again and erasable recording of a recording film enrolment

摘要

In a rewritable recording apparatus using a recordingmedium 1 having a recording layer which exhibits a colordeveloping property when a first kind of heat energy isapplied thereto and a tone reducing property when a secondkind of heat energy is applied thereto, a recording-energisation control section 34 supplies an image recordingsignal corresponding to a desired display image to a heatingdevice 3 to cause it to generate heat with the first kind ofheat energy. This heating device 3 imparts the first kindof heat energy to the recording medium 1, whereby a desireddisplay image is recorded on the recording medium 1. Anerasure control section 35 supplies an imageerasing signal corresponding to a desired erasing range tothe heating device 3 so as to cause it to generate heat withthe second kind of heat energy. This heating device 3imparts the second kind of heat energy to the recordingmedium 1, whereby the image recorded on the recording medium1 is erased.
