Abstract
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 disposed 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.
