ABSTRACT Cassette with Controlled-speed Elastic Belt In a tape transport apparatus comprising notably a floating roller (12) tangent to reels (5, 6), and an elastic endless belt (11) extending be- tween the floating roller (12) and the reels (5, 6) to form a first loop (11a) surrounding the floating roller (12) and a second loop (11b) engaging on an arc of the periphery of each of the reels (5, 6) to maintain the tension of the accessible portion of the tape (7), this second loop (11b) extending around at least one return roller (13, 14), the invention provides that at least return roller (14) is directly driven by drive means (18, 19), whereby the peripheral speed of the driven return roller (14) and the peripheral speed of the floating roller (12) are maintained in a ratio slightly greater than 1, so as to ensure better tensioning of the tape on the take-up reel.
