Abstract

L'invention concerne un dispositif de protection de disque support optique (10) comprenant un disque en plastique transparent (2, 20) présentant une configuration sensiblement circulaire et pourvu d'un trou (12) en son centre. Dans un mode de réalisation, un adhésif temporaire hydrosoluble (4, 6), appliqué sur un côté du disque en plastique (2) au niveau de l'anneau intérieur, adjacent au trou central (12), et de l'anneau extérieur périphérique, fixe le disque en plastique (2) sur le disque support optique (10). Dans un autre mode de réalisation, des bandes adhésives temporaires autocollantes (22) fixent le disque en plastique (20) sur le disque support (10). Le laser d'un lecteur de disque classique peut alors lire le contenu d'un disque support optique (10) à travers le disque en plastique (2, 20). Si un dispositif de protection de disque est endommagé, il peut être facilement retiré et remplacé.
