Abstract
This invention provides a method for producing a CD-R optical recording medium. A first stack at a first stage is created by forming on a substrate a recording layer containing an organic dyestuff and a metal layer. At least after a formation of the metal layer; the first stack is transported from the first stage along a transport path towards a second stage through an atmosphere having a relative humidity. The relative humidity is maintained at 40% or less. To control the relative humidity, a shielding plate may be provided around the transport path. An air conditioner may locally control the relative humidity of an area encircled by this shielding plate.
