METHOD AND APPARATUS FOR PRODUCING SPECIAL MOTION EFFECTS IN VIDEO RECORDING AND REPRODUCING APPARATUS

摘要

A method and apparatus for producing special motion effects such as slow and fast motion, still frame and other effects from video magnetic tape is disclosed which is particularly applicable to helical wrap recording and reproducing apparatus. The apparatus employs a transducing head that is mounted on a revolving scanning drum, with the head being movable in a line generally transverse to the recorded track. The present invention utilizes the transverse positioning of the head to accurately follow a track during reproducing or playback and, at the completion of the track, to properly position or set the head in position to either play the next adjacent successive track, replay the same track, or play yet another track so that special motion effects can be achieved without experiencing picture breakup or unwanted noise.
