Title (EN) INFORMATION STORAGE MEDIUM
(FR) SUPPORT DE MEMORISATION D'INFORMATION
Abstract:
(EN) An information storage medium wherein much more data can be written at high density and which is hard to fabricate or steel and therefore is very reliable. The information storage medium is made by stacking, on a transparent resin substrate (2), a metal reflection layer (3) wherein light reflected data can be written and a magnetic storage layer (5) wherein magnetic data is written.
(FR) Support de mémorisation d'information permettant d'enregistrer un nombre beaucoup plus important de données à densité élevée et présentant une conception sophistiquée, ce qui le rend très difficile à dérober et lui confère une fiabilité élevée. On fabrique ce support d'information par empilement, sur un substrat (2) en résine transparente, d'une couche réfléchissante métallique (3), dans laquelle peuvent être enregistrées des données de réflexion lumineuse, et d'une couche de mémorisation magnétique (5), dans laquelle sont enregistrées des données magnétiques.
