A belt driven reel-to-reel tape cartridge having a belt which is mounted around a drive roller and rotatable guide rollers, the belt contacting the tape reels to drive the tape reels on respective tape reel pins wherein the tape is convolutely wound on the tape reels in opposite directions, the tape cartridge comprising:
- a front edge wall which provides access to the tape by a recording head;
- and
- a tape guide system comprising:
- first and second primary tape guides mounted along the front edge wall for guiding the tape to and from respective tape reels;
- a guide pin disposed intermediate the first and second primary tape guides and along the front edge wall for guiding the tape;
- and
- a first secondary tape guide mounted between the first primary tape guide and its respective tape reel, wherein the tape guides and guide pin define a tape guide path between the reels and wherein the tape guide path extends around the outside of both primary tape guides, the secondary tape guide, and the guide pin, and wherein the distance between the first secondary tape guide and the first primary tape guide is half the distance between the first primary tape guide and the guide pin to help minimize tape tracking variations.
