Abstract

La présente invention concerne un procédé et un appareil permettant de produire à faible coût un support d'enregistrement optique qui comprend une couche intermédiaire possédant une bonne surface ondulée et uniquement quelques défauts. Plus spécifiquement, une couche d'enregistrement est formée directement sur un substrat ou via une autre couche, et une couche de résine est formée directement sur la couche d'enregistrement ou via une autre couche. Puis une matrice de pressage qui présente un motif ondulé à former est placée sur la couche de résine et, un corps collé est obtenu par durcissement de cette couche de résine. Ensuite, la matrice de pressage est séparée de la couche de résine alors que le corps collé est chauffé, formant ainsi la couche de résine en une couche intermédiaire possédant un motif ondulé transféré.
