ABSTRACT:
An object of the present invention is to provide an optical information recording medium by which the getting thereof in and out of a reproducing apparatus and the reproducing of recoding data can be stably and reliably performed and the recording content can be visually confirmed, and which has the reversible display function of performing at least one of the recording, erasing and rewriting of the display which is excellent in the uniformity of the image, easily, with a good appearance and without damaging the optical information recording medium; a manufacturing method of the above-noted optical information recording medium; and an image processing method using the above-noted optical information recording medium. For this object, the present invention provides the optical information recording medium comprising a substrate, an optical information layer disposed on the substrate and a reversible thermosensitive layer in which at least a part of the information recorded in the optical information layer can be recorded in such a manner that the part of the information can be visually recognized, in this order; and further a cushion layer in at least a part of the space between the optical information layer and the reversible thermosensitive layer.
