<P>PROBLEM TO BE SOLVED: To provide an optical information recording medium having excellent characteristics of jitter, noise and the like and high reliability, and also to provide its manufacturing method. <P>SOLUTION: In the manufacturing method of the optical information recording medium, having a light-reflective layer, a recording layer on which information is recordable by a laser beam having a wavelength of ≤450 nm, an adhesive layer containing an adhesive, and a cover layer successively disposed on a substrate, the recording layer has coloring matter. The manufacturing method has a light-reflective layer forming step for forming the light-reflective layer by sputtering a light-reflective substance with 0.1 to 10 kW sputtering power and 1.67×10<SP>-3</SP>to 1.67 cm<SP>3</SP>/sec argon flow rate on the substrate. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
