Abstract: An optical data storage medium comprises a substrate having thereon concavities and convexities so that diffraction of reflected light is caused; a reflective layer having a high regular reflectance; and a colored region which is provided by applying transparent coloring ink to the reflective layer so that the regular reflectance of the reflective layer on the side opposite to the substrate side falls within a range of from 3 to 80%. The external appearance of the optical data storage medium provides a visual effect utilizing metallic gloss and light-diffraction-based iridescent reflection characteristics which result from the reflective layer provided on the substrate having concavities and convexities.
