Abstract
PURPOSE: To produce the disk by a method wherein a photo-setting covering layer having plasticity is coated on a plastic or glass plate, then a stamper having minute ruggedness is laid on the coated film, and after pressure molding, ultraviolet rays are irradiated and the stamper is released.
CONSTITUTION: The photo-setting covering layer having plasticity is coated on the plastic or glass plate, then it is subjected to pressure molding in the condition of being laminated with the stamper having minute ruggedness cut thereon, and ultraviolet rays are iradiated from the side of the plastic or glass plate to set the coated film, followed by releasing the stamper. Accordingly, a duplicate disk for information recording can be produced without using any high-temperature treatment, while securing a high producitivity and enabling energy conservation in the production steps.
