<P>PROBLEM TO BE SOLVED: To provide an optical information recording medium having a reversible display function by which display can be easily recorded, erased and rewritten with good appearance without giving damage to the medium by a heat hysteresis in printing, wherein loading into and unloading from a reproducing device and reproduction of recording data can be stably and reliably performed and storage contents of the medium can be visually confirmed. <P>SOLUTION: (1) The optical information recording medium has an optical information storage layer part having a transparent substrate with an optical guide groove and a reversible display recording layer part and has a heat insulation layer between the optical information storage layer part and the reversible display recording layer part. (2) The optical information recording medium has an optical information storage layer part having a transparent substrate with an optical guide groove and a reversible display recording layer part and the reversible display recording layer part is constituted of a support, a reflection layer, an adhesion layer, a recording layer and a protective layer and has a heat insulation layer relaxing influence of heat on the support between the support and the reflection layer, or the reversible display recording layer part is constituted of a support, a recording layer and a protective layer and has a heat insulation layer relaxing influence of heat on the support between the support and the recording layer. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
