<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical information recording medium which has excellent recording characteristics with less variations in recording, and an optical information recording medium manufactured by this method, and an optical information recording method therefor. <P>SOLUTION: This manufacturing method of an optical information recording medium includes a step of forming a layer in vacuum on a base plate of 0.7-2 mm thick, a step of forming a pigmented layer by applying pigment containing liquid on this layer formed in vacuum, and a step of providing a cover layer of 0.01-0.5 mm thick on this pigmented layer. The temperature of the coating plane of the above pigment containing liquid is 10-40°C. The optical information recording medium is manufactured by this manufacturing method. A laser beam of a 100-600 nm wavelength is projected from the above cover layer side to the optical information recording medium manufactured by this manufacturing method to record information by forming pits on the above pigmented layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
