Abstract: Disclosed is an optical recording medium which can increase the gloss of a print receptive layer provided on a level surface and can provide a high quality print. An optical recording medium (200) comprises a record-reproducing layer (10) which is a substrate-incident medium and a print receptive layer (20) which can be printed with an ink and is provided on the surface opposite to the surface of the record-reproducing layer (10) which receives the irradiation with light. The print receptive layer (20) comprises a filler-containing layer (22) which contains a hydrophilic resin and an organic or inorganic filler as main ingredients and a non-filler-containing layer (21) which is laminated on the filler-containing layer (22) and contains no organic or inorganic filler.

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 medium 100 having such a structure that on a substrate 101, an electronic information recording layer 102, a reflective layer 103 formed in contact with the opposite side of the electronic information recording layer 102 from a side where a laser beam 107 enters, a protective layer 104, a visual information recording layer 105 and an overcoat layer 106 constituting 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%.

Abstract: An optical information-recording medium includes: a substrate; an electronic information-recording layer on the substrate in which digital information is recorded by the light applied from the side of the substrate; a reflection layer on the electronic information-recording layer; a visible information-recording layer on the reflection layer so that a region of the visible information-recording layer lays outside a circumference having a radius not less than half a radius of the substrate; and an over-coating on the visible information-recording layer. Visible information is recorded in the visible information-recording layer with light applied through the over-coating.
