    Abstract: A process for producing a substrate (1) for an optical recording medium, equipped with a structured front face and a rear face, comprises: the formation of an upper layer (3), composed of a crosslinkable hybrid organic/inorganic material, obtained by a sol-gel process and that is solvent-free, on a first planar surface (2b) of a lower layer (2) comprising a second planar surface (2a), opposite to the first surface (2b) and forming the rear face of the substrate (1), and the formation of the structured front face of the substrate, by structuring a free face of the upper layer (2) and by crosslinking the crosslinkable hybrid organic/inorganic material.

    Abstract: The recording medium comprises at least a first (L1) and a second (L2) micro-structured stage assembled by an adhesive layer (4) and arranged between micro-structured bottom (2) and top substrates. A polymerizable layer forming the adhesive layer (4) is deposited on the first stage (L1). Then a micro-structured transparent matrix (5) is provisionally placed on the adhesive layer (4) so as to micro-structure the adhesive layer (4). Polymerization of the adhesive (4) is performed by exposure, through the matrix (5), with a polymerization light. Then the matrix (5) is removed and the second stage (L2) is deposited on the micro-structured adhesive layer (4). Then an additional adhesive layer (9) is deposited on the second stage (L2) and the micro-structured matrix (5) is definitively placed on the additional adhesive layer (9) so as to form the top substrate.
