(EN) DISC-SHAPED INFORMATION CARRIER WITH A HIGH STORAGE DENSITY
(FR) SUPPORT D'INFORMATIONS EN FORME DE DISQUE A HAUTE DENSITE DE MEMOIRE
Abstract
(DE)
Erfindungsgemäß wird dem Endkunden ein scheibenförmiger Informationsträger (1) hoher Speicherdichte mit mindestens einer unverschmutzten und beschädigungsfreien Leseseite (5) dadurch zur Verfügung gestellt, dass jede Leseseite (5) mit einer flexiblen, adhäsiven Schutzfolie (11) versehen ist. Diese Schutzfolien (11) sind durch den Endkunden rückstandslos abziehbar und können vorteilhaft als Werbeträger mit Bildern und Texten, aber auch mit digitalen Datenspuren ausgestattet sein. Ein Gerät kann zunächst auf die Folien fokussieren, um dann von ihnen Informationen zu lesen oder auf sie zu schreiben. Die aufgeklebten Folien können auch ganzflächig und mehrschichtig für digitale Informationen genutzt werden.
(EN)
According to the invention, an end user is provided with a disc-shaped information carrier (1) having a high storage density and at least one clean and undamaged read side (5) which is covered by a flexible, adhesive protective film (11). Said protective films (11) can be torn off by the end user without leaving any residues and can be provided with images or texts or digital data tracks as an advertising medium in an advantageous manner. A device can firstly be focused onto the films and can then read information thereon or write thereon. The entire surface of the glued films and several layers of said films can be used for digital information.
(FR)
L'invention est caractérisée en ce qu'un utilisateur final dispose d'un support d'informations en forme de disque (1) à haute densité de mémoire, ayant au moins une face de lecture (5) propre et non endommagée, du fait que chaque face de lecture (5) est munie d'un film de protection souple et adhésif (11). Ces films de protection (11) sont pelables, sans traces de résidus, par l'utilisateur final et peuvent être avantageusement réalisés sous forme de supports publicitaires avec des images et du texte ou avec des traces de données numériques. Un dispositif peut tout d'abord être focalisé sur les films pour lire des informations émanant de ceux-ci ou en écrire sur ceux-ci. Les films collés peuvent être utilisés sur toute leur surface et en plusieurs couches pour des informations numériques.
