An apparatus for presenting visual information and corresponding audio information simultaneously utilizes an audio-visual slide which includes a transparency for projection and a movable endless magnetic tape of relatively great recording capacity. The apparatus includes projecting means for the transparency of the slide, driving means for moving the slide to the projecting position in the projecting means and returning the slide to its original position, tape driving means for driving the magnetic tape in the slide when the slide is in the projecting position, and reproducing means adapted to be urged into contact with the magnetic tape to reproduce audio information on a spiral track of the tape with the aid of a magnetic head. |
