CA 2311832

An information recording apparatus comprises a vacuum chamber, an energy beam generator emitting an energy beam for recording information on a substrate in the vacuum chamber, a spindle motor rotating the substrate in the vacuum chamber, a movable holder dis-posed in the vacuum chamber for carrying the spindle motor, and a feed motor unit connected to the movable holder for linearly moving the substrate in a vacuum atmosphere within the vacuum chamber. The holder, the vacuum chamber, and the energy beam generator are fixed to a common plate-shaped base member. The feed motor unit is connected to the movable holder by means of a hollow rod, a flexible sleeve element being provided over the rod between the feed motor unit and the vacuum chamber wall.

Un dispositif d'enregistrement d'information comprend les éléments qui suivent. Une chambre à vide, un générateur de faisceau d'énergie émis pour enregistrer de l'information sur un support de la chambre à vide; un moteur à axe faisant tourner le support dans la chambre à vide; un support mobile placé dans la chambre à vide pour porter le moteur à axe; et un moteur d'alimentation raccordé au support mobile pour déplacer linéairement le support dans l'atmosphère de vide qui règne à l'intérieur de la chambre à vide. Le support, la chambre à vide et le générateur de faisceau d'énergie sont fixés à un élément commun de base en forme de plaque. Le moteur d'alimentation est raccordé au support mobile au moyen d'une tige creuse, un élément à manchon souple occupant le dessus de la tige, entre le moteur d'alimentation et la paroi de la chambre à vide.
