Verfahren und Einrichtung für die Herstellung eines biegbaren optischen Informationsaufzeichnungsmediums.

摘要

A flexible optical information recording medium consists of a flexible resin layer having a corrugated pattern on its surface corresp. to the information to be recorded, and a reflection layer which is formed on the corrugated pattern of the resin layer and has light reflecting property. A flexible support layer supports the resin layer. To produce the flexible optical information recording medium, a resin soln. which is cured upon radiation of U.V. or electron beam is packed between the U.V. or electron beam-transmissible substrate film as the support layer, and a corrugated pattern original, and after this resin film is cured and shaped on the substrate film by radiating the U.V. or electron beam through the substrate film, the resulting cured film is peeled off. Another prodn. method comprises forming a resin layer which is cured by irradiation with U.V. or electron beam and has thermal mouldability on a U.V. or electron beam-transmissible substrate film, forming then a roll-shape transfer film, bringing the resin layer surface of this transfer film into pressure contact with a corrugated pattern forming surface of the original while heating it, performing the transfer of the corrugated pattern while the resin layer is being softened, radiating then a U.V. or electron beam through the substrate film, curing the softened resin layer and peeling off the transfer film from the original. A flat sheet-like adaptor is used in order to reproduce such a flexible optical information recording medium. Reproduction can be made particularly effectively by clamping the medium with a lower surface adaptor and an upper surface adaptor.
