CONSTITUTION: In an optical information recording medium, a transparent substrate 1 in which uneven parts corresponding to information signals are formed is coated with a pigment-containing paint which is composed mainly of a pigment material and of a polymer material, and a pigment-containing layer (a reflection layer) 3 at a reflectance of 15 to 25% is formed. In the optical information recording medium, titanium alkoxide or its polymer as an additive has been added, in a ratio of 5 to 10wt.% with reference to the polymer material, to the pigment-containing paint.

Abstract: PURPOSE:To obtain an optical recording medium applicable to various recorder/ reproducer employing a low reflectance medium with no limitation on the wavelength of reproduced light by employing a film of titanic polymer having a specified structure in a reflective layer. CONSTITUTION:A reflective layer 3 is formed on a substrate 1 on which pit parts 2a, corresponding to information signals, guide grooves, and address code pits are formed along with land parts 2b. Information is read out by detecting the difference in the quantities of light reflected from the pit part 2a and the land part 2b when the reflective layer 3 is irradiated with a laser light L from the substrate 1 side. The reflective layer 3 is formed of a film of titanic polymer material represented by a general formula shown in the drawing. The optical recording medium constantly exhibits a reflectance in the range of 15-25% having low wavelength dependency for the wavelength in the range of 400-900nm. This optical recording medium can be applied to various recorder/ reproducer employing a low reflectance medium being limited by the wavelength of reproduced light.
