Abstract: A multipurpose audio-visual film handling cassette is provided wherein an audio information bearing magnetic tape is interwound with a photographic film strip upon coplanarly mounted supply and takeup spools and wherein the film strip and the audio tape are passed along different paths for photographic and audio operations to be performed thereon. The film strip and the magnetic tape are interconnected and advanced through the multipurpose cassette in a manner such that a free tape loop is formed exterior of the cassette at an audio station during the exposure/recording and project/playback modes of operation of the cassette. The manner of interconnection between, and the respective paths of the tape and film strip, result in the disappearance of the tape loop at the end of each of these operational modes and still further, no loop is formed exterior of the cassette during the processing and subsequent rewind modes of operation.
