Optical recording and/or reading device with spindle and optical elements supported on parallel bars

Apparatus for recording and/or reading information on a disc by means of a radiation beam, which disc is rotatable about an axis of rotation, which apparatus comprises:

• a stationary frame,
• a drive means for the rotary drive of the disc, which drive means comprises a drive spindle which is rotatable about said axis of rotation and a stationary spindle support system provided with bearing means for the drive spindle,
• a slide which is movable in a radial direction relative to said axis of rotation,
• a parallel-guide arrangement for the slide, which arrangement comprises two parallel guides which are detachably secured to the frame at some distance from each other and,
• an opto-electronic system stationarily arranged with respect to said parallel guides comprising a light source, one or more optical elements, and means for effecting a conversion between optical and electrical modulation of the information,
• at least one of said systems being supported by the two parallel guides, and being provided with locating stops which cooperate with the guides for an accurate positioning.
