ABSTRACT:
A method for producing an optical information recording medium includes the steps of: coating a solution for forming a dye recording layer onto a surface of a rotating disc-shaped resin substrate; and discharging a cleaning solution from a nozzle onto a peripheral edge to remove the dye recording layer from the peripheral edge, wherein discharge of the cleaning solution is initiated 1.0 to 300 seconds after completion of the coating, and the nozzle is disposed on a plane that extends in a normal line direction of the substrate and includes a straight line representing a discharge direction of the cleaning solution, so that an angle defined by the discharge direction and the normal line is 0 to 60°.
