ABSTRACT:
A tape cartridge has a roller driven continuous belt which supports a wide thin tape when transported in the vicinity of video recording machine heads. A spring biased movable belt idler applies a predetermined amount of tension to the belt thus keeping the tension in the belt constant regardless of changes in temperature, humidity, etc. Since the belt both supports and supplies constant tension to the tape, tape bounce, tape breakage, tape stretch and tape wear are minimized and the manufacturing tolerances of the belt are significantly improved.
