A belt driven tape cartridge employs a pair of tape reels on fixed spaced axes within a cartridge case and on which a tape extending between them is convolutely wound to form tape rolls. Tape is transported between reels when the reels are driven by a taut belt that extends between the rolls and around a drive roller at one side of a line connecting the tape reel axes and around an idler roller at the other side of that line. The drive roller rotates on a fixed axis which in preferred form is equidistant from the two tape reel axes. The idler roller rotates on an axis that is parallel with the other axes but is free to move laterally.
