ABSTRACT:
To provide an optical information recording medium on which visual information can be recorded on a label face side by using a laser apparatus for recording and reading electronic information by irradiation with a low output laser without exerting, e.g. thermal influence over electronic information recorded on the medium. The optical information recording medium of the present invention is an optical information recording medium100having such a structure that on a substrate101, an electronic information recording layer102, a reflective layer103formed in contact with the opposite side of the electronic information recording layer102from a side where a laser beam107enters, a protective layer104, a visual information recording layer105and an overcoat layer106constituting an outermost layer are laminated in this order, and having a reflectivity against a beam applied from the label face side of at least 15 and at most 50%.
