ABSTRACT:
A belt driven reel-to-reel tape cartridge includes two tape guides for guiding the tape to and from respective tape reels. The tape guides have a large radius of curvature and are flanged to form a long trough to guide and align the tape to improve tape tracking. This also provides hydrodynamic lift by creating an air film between the tape and the tape guide to reduce the friction between the tape backside and the tape guide. The radius of curvature can be constant or can vary from a larger radius at the ends to a smaller radius in the middle.
