Title (EN) AN OPTICAL MEMORY DEVICE AND A METHOD OF MANUFACTURING THEREOF
(FR) MEMOIRE OPTIQUE ET SON PROCEDE DE FABRICATION
Abstract:
(EN) The optical memory device has at least one data layer formed on a substrate. An upper surface of the substrate is formed with a pattern comprising a plurality of regions, which are capable of obtaining, when covered by a recording medium, desired optical properties different from those of the substrate. The patterned surface of the substrate is coated with the recording medium. The recording medium is removed from the patterned surface after the recording regions have obtained the desired optical properties.
(FR) Mémoire optique et son procédé de fabrication. Cette mémoire optique possède au moins une couche de données qu'on a créé sur un substrat. On crée sur une surface supérieure du substrat une configuration composée d'une pluralité de zones capables d'acquérir, lorsqu'on les recouvre d'un support d'enregistrement, des propriétés optiques souhaitées différentes de celles du substrat. On recouvre la surface du substrat comportant la configuration par le support d'enregistrement. On enlève ce support d'enregistrement de la surface comportant la configuration après que les zones d'enregistrement aient acquis les propriétés optiques souhaitées.
