Abstract
A two-reel tape cartridge in which an elastic belt extends around guide rollers adjacent the reels and a driving roller between the reels and contacts the tape on the reel hubs. The tape path between the reels is spaced from the drive belt and extends across a cutaway portion along one edge of the cartridge for access by a transducer. Tape wrap pins in the tape path adjacent each reel make less contact with the tape as more of the tape is transferred from the adjacent reel serving to make the tape tension at the transducer quite uniform as the tape is transferred from one reel to the other.
