Abstract: A transport mechanism for a strip of flexible recording tape. The mechanism includes a support having a loop-shaped passageway formed therein. The passageway has a predetermined length and is structured to receive an elongated discontinuous strip of flexible tape having a length slightly less than the median length of the passageway. When the strip of tape is placed in the passageway, the free ends of the strip are closely adjacent to each other. A pneumatic driving force is applied to this tape strip to operate it within the passageway. The tape strip moves through the passageway in a manner very similar to a continuous tape loop.
