A supporting device for data-storage optical discs which includes a rest plate with which at least one supporting element is arranged to receive an optical disc. The supporting device further includes a vacuum assembly and vacuum connecting through-holes for providing vacuum communication between the supporting element and the vacuum assembly. The supporting element includes a base and a side wall arranged to support the optical disc and defining, with the optical disc itself, a vacuum chamber. The vacuum chamber ensures locking retention of the optical disc on the supporting element, while enabling movement of the rest plate, and further achieves cooling of the disc by an air stream passing through the chamber and spreading over the optical disc surface.
Dispositif de soutien pour disques optiques de stockage de données. Comprend une plaque d'appui sur laquelle repose au moins un élément de soutien afin de recevoir un disque optique. En outre, le dispositif de soutien comprend un montage à vide et des trous de passage de connexion à vide permettant de faire communiquer à vide l'élément de soutien et le montage à vide. L'élément de soutien comprend une base et une paroi latérale disposées de façon à soutenir le disque optique et définissant, avec le disque optique lui-même, une chambre à vide. Cette chambre à vide assure le blocage en place du disque optique sur l'élément de soutien, tout en permettant le mouvement de la plaque d'appui et la circulation d'un courant d'air qui permet de refroidir le disque en balayant sa surface.
