<p>A limited-use tape cassette includes a follower arm (420) pivotally secured to the housing at one end (422) while abutting the spooled tape (8) of a cassette reel (6) at a distal end. A use-limiting mechanism is provided by the follower arm (420) or another inter-related arm to control rewinding and/or playback of the tape based on follower arm position and/or positional history. In one embodiment, a second rotatable arm (30) is located in controlled interference with the follower arm so as to cause it to 'lock up' after a predetermined number of unfettered play back/rewind cycles have taken place. In other embodiments, the arrangement (Fig. 12) utilizes existing brake teeth of a tape cassette reel to prevent rewinding after a predetermined amount of the video has been viewed.</p> |
