Abstract
A subambient pressure feature for assisting in guidance of storage tape within a tape transport system such as a data storage tape cartridge and/or a tape drive. The storage tape is extended between two tape reels along a tape path defined, in part, by a tape guide. The tape guide includes a curved tape-receiving surface defined by an entrance side and an exit side. The subambient pressure feature is located along the tape path and is adapted to induce frictional engagement between the tape and at least a portion of the tape-receiving surface at speeds of not less than 1 meter/second to suppress lateral tape motion.
