ABSTRACT:
A method of manufacturing an information carrier which cures an adhesive by means of UV radiation in an inert-gas atmosphere. The adhesive is interposed as an adhesive layer between two superposed layers of a disc-shaped information carrier. The device includes a UV source, a supplier for an inert gas, and a holder for holding the information carrier in a centered position with respect to a centering axis. The inert-gas supplier has discharge openings for inert gas, situated in a circular zone around the centering axis, at a distance from the centering axis which substantially corresponds to the radius of the peripheral edge of the information carrier, so as to cause inert gas to flow past the peripheral edge during curing, as a result of which locally present oxygen which would interfere with curing is expelled.
