ABSTRACT:
Disclosed is an apparatus for recording information on and/or reproducing information from a disk-like recording medium with a light beam. The apparatus includes a box-like casing in which are provided a rotary drive mechanism for rotating the recording medium, an optical head having a movable portion on which at least an objective lens is mounted and a fixed portion on which at least the light source for emitting the light beam and a detector for detecting light reflected by the recording medium are mounted, and an electric circuit board having at least a control circuit for controlling the conditions of irradiation of the recording medium with the light beam and the movement of the optical head. Shielding plates are provided to separate the recording medium and the movable portion of the optical head from the rotary drive mechanism, the electric circuit board and the fixed portion of the optical head, and a cooling fan is also provided to cool the rotary drive mechanism, the electric circuit board and the fixed portion of the optical head.
