OPTICAL INFORMATION RECORDING MEDIUM

摘要

There is provided an optical information recording medium capable of recording visible information on a label surface by a low-out laser radiation by using a laser device for recording/reproducing electronic information without thermally affecting the electronic information recorded on the medium. The optical information recording medium (100) includes a substrate (101) and layers successively formed on the substrate: an electronic information recording layer (102), a reflection layer (103) arranged in contact with the a side of the electronic information recording layer (102) opposite to the side where a laser beam (107) is incident, a protection layer (104), a visible information recording layer (105), and an overcoat layer (106) forming the outermost layer. The reflection ratio of light applied from the label surface side is not smaller than 15 and not greater than 50%.
