PURPOSE: To obtain a flexible replica with low cost and high accuracy in short working treatment-time by separating an original disk from resin layer, after radioactive rays are made to irradiate on the radioactive ray-curing resin layer at the state in which said resin layer has been formed on the original of the photodisk.

CONSTITUTION: The signal surface of a photodisk becoming an original disk 1 is coated by 10W200μm thick with the radioactive ray-curing resin such as acryl or polyester resin by means of screen printing method, and resin layer 2 is formed. Then, the radioactive ray such as strong ultraviolet ray is made to irradiate on said resin layer 2 under nitrogen atmosphere by using a violet ray lamp 3 at the state in which the radioactive ray-curing resin layer is provided on the original disk 1, whereby the resin layer 2 is cured. Then, the objective flexible replica is obtained by separating said original disk 1 for a photodisk from said resin layer 2.
