PROBLEM TO BE SOLVED: To improve the visibility of display contents by providing the recording medium with >=2 reflection layers having reflection spectra varying in a visible region and displaying character information in such a manner that the information is recognizable when viewed by man. SOLUTION: Information surfaces 2 are composed of pits and are spirally recorded with the information from the center of a disk. The display contents which indicate the contents associated with the recorded information and are composed of characters or designs are so formed that the recognition by man is made possible by first reflection layers 3 on the information surface 2. The first reflection layers 3 are covered by second reflection layers 4 having the reflection spectra in the visible region different from the reflection spectra of the first reflection layers 3. Further, the second reflection layers 4 are covered by protective layers 5. An adhesive layer 6 which is a UV curing type resin, etc., is applied on the protective layer 5 of the one optical information recording medium of two sheets of the optical information recording media formed in such a manner and the protective layer is superposed and adhered on the protective layer 5 of another optical information recording medium in order to form the sticking type optical information recording medium. |
