PROBLEM TO BE SOLVED: To provide an optical information recording medium with which is good in reproducibility in recording and reproducing characteristics and has excellent durability under a wide temperature and humidity environment. SOLUTION: The period summing up a discharge period from the point of time t0 when a dyestuff recording layer is formed by applying a dyestuff solution on a substrate until the point of time t1 when the substrate is placed on a stack pole, a preservation period when the substrate is preserved in the state of placing the substrate on a stack pole, and a feeding period from the point of time t2 when the substrate is removed from the stack pole until the point of time t3 wen the substrate is fed to a sputtering mechanism after the stack pole is transported to the next post treatment equipment is specified to >=30 minutes to <=24 hours. The substrates are maintained in the environment of 15 to 35 deg.C during these periods. |
