HIGH DENSITY INFORMATION RECORDING CARRIER USING RESIN CURED BY ULTRAVIOLET RAY IRRADIATION

摘要

PURPOSE:To economically form a thickened high density information recording carrier, by sticking a signal recording sheet made of resin cured by ultraviolet ray irradiation, to both the surfaces of a core material having rigidity. CONSTITUTION:A resinous layer which is curable by ultraviolet rays painted on the base film with uniform thickness is pressed by the stamper. After the resin is cured by irradiation of the ultraviolet ray, the base film is peeled off and removed, then a sheet having a pit row 6 on which a concavo-convex signal of the stamper has been transferred is formed, subsequently a metal is vapor-deposited on a signal recording surface 4 of said sheet to form a thin metallic film 7. Subsequently, a signal recording layer 3 is formed by sticking said sheet onto both sides of a core material (i.e. metallic sheet, glass plate etc.) 1 having rigidity so that a recording surface 4 comes to the inside through an adhesive layer 2. In this way, a recording carrier is obtained.
