  • Patent number: 5734538
    Abstract: A belt-driven tape cartridge has a rectangular housing with a front wall shorter than its side walls. The front wall has an access opening for a tape read/write head and a drive opening. A pair of tape spools are rotatably mounted in the housing so as to lie on an axis oriented at an angle to the front wall, and a plurality of tape guides define a tape path between the spools and across the access opening. An endless drive belt extends around a drive roller at the drive opening and at least three belt guide rollers in a belt path arranged to contact tape on each spool. The tape path has extended portions extending between the tape contacting portions on each side of the spools. At least one belt guide roller is located in the same extended portion of the belt path as the drive roller, and at least two belt guide rollers are located in the other extended portion of the belt path.
