Abstract:
A method for producing a CD-R optical recording medium, steps in the method being conducted along a transport path, the method comprising:forming a recording layer by spin coating an organic dyestuff on a substrate; drying the recording layer using an oven; forming a reflective film on the recording layer using a sputtering device to form a first stack; transporting the first stack along the transport path towards a spin coater through an atmosphere having a relative humidity, providing a shielding plate along both sides of the transport path which encloses the transport path at least from the sputtering device to the spin coater, and controls air flow from above the transport path onto the enclosed transport path between the sputtering device and the spin coater; controlling the relative humidity only in the enclosed transport path such that the relative humidity is not more than 40%; and applying a protective film using the spin coater, to the first stack.
