The invention relates to a method for producing optical storage media, for example of the CD type, in an at least semi-continuous manner. The inventive method comprises the following steps: continuously coating a plastic film strip (2) with a liquid, UV-curable material, drying the coating by supplying heat until the coating reaches a state in which it is no longer flowable but can still be impressed, and providing the substrate in the shape of a strip. A surface relief (21a) corresponding to the information to be stored can be impressed on said strip either directly after production of the strip or after a temporary storage. The strip can be impressed between two rolls (9, 10), the roll facing the coated side of the strip being provided with the surface relief. The coating is then cured under exposure to a UV radiation source (11).

L'invention concerne un procédé permettant au moins une fabrication semi-continue de supports d'enregistrement optiques, de type disque compact par exemple. Ce procédé regroupe les étapes suivantes, revêtement continu d'une bande de pellicule plastique (2) avec un matériau liquide durcissable aux UV, et séchage consécutif du revêtement par amenée de chaleur jusqu'à ce que le revêtement ne puisse plus s'écouler mais encore être estampé. On obtient alors un substrat en forme de bande pouvant immédiatement ou après stockage intermédiaire, être pourvu d'un relief surfacique (21a) correspondant aux informations à enregistrer. L'estampage peut être effectué entre deux rouleaux de presse (9, 10), le relief surfacique étant porté par le rouleau orienté vers le côté de revêtement de la bande. Ledit procédé s'achève par durcissage du revêtement sous l'action d'une source de lumière UV (11).
