Horvath discloses an audio-visual system in which audio-visual cartridges are inserted into a housing that resembles a television set and has a rear-projection screen. The cartridge contains a circular disc on which photographic images are recorded and an endless magnetic tape on which are recorded audio signals and control signals. Detection of a control signal results in a brake pawl being momentarily removed from one of the brake notches in the edge of the circular disc, thereby allowing the disc to be rotated by the drive motor to the next brake notch so as to display the next picture (col. 7, lines 13-39). The drive motor is a continuous motor rather than a stepping motor. Hattori discloses goggles which include liquid-crystal display devices and earphones. The audio and video signals may be provided by television receiving circuitry. The examiner also contends that it is well known in the art to use a stepping motor in a film projector (Answer at 4).
