Abstract

Un porte-enregistrement sur lequel l'enregistrement s'effectue à l'aide d'un faisceau de rayons utilise un disque ou un tambour transparent, un disque ou un tambour de support coaxial et deux anneaux d'étanchéité élastiques coaxiaux pour former une enceinte entre les disques ou les tambours. Un milieu d'enregistrement sensible au rayonnement appliqué sur la face du disque ou du tambour se trouvant à l'intérieur de l'enceinte est ainsi protégé des particules de poussière ambiante et d'autres matières polluantes, tandis que les sous-produits gazeux ou solides de l'interaction entre le milieu d'enregistrement et le faisceau de rayons dans la zone entourant la zone d'impact du faisceau, sont en substance confinés entre les surfaces des disques et ne peuvent pas produire de dépôt sur un objectif utilisé pour focaliser le faisceau de rayons ni intoxiquer l'utilisateur.
