Abstract: A single reel data storage tape cartridge is described that includes a housing having a tape access window. A single tape reel assembly is rotatably disposed within the housing and includes a hub about which a storage tape is wrapped. A tape guide is disposed within the housing adjacent the single tape reel assembly, opposite the tape access window, and is configured to define a pathway of the storage tape from the single tape reel assembly to the tape access window and limit lateral motion of the storage tape.

Abstract: A tape guide for limiting lateral tape movement within a tape transport system component, such as a data storage tape cartridge. The storage tape, having a tape width, extends between two tape reels along a tape path defined, at least in part, by the tape guide. The tape guide includes a tape contact face, a top flange and a one bottom flange. The tape guide is configured to define an effective tape path width between the top and bottom flanges that is less than the tape width. During use, the tape guide biases the tape path to minimize lateral motion of the storage tape.

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.

Abstract: A tape guide for use in a tape transport system, such as a data storage tape cartridge or a tape drive. The storage tape extends from the tape reel along a tape path that includes the tape guide. In this regard, the tape guide includes a tape contact face and at least one guide flange. Extension of the guide flange relative to the tape contact face defines an angle of not less than 90°. With this configuration, an edge of the storage tape is directed to move along the guide flange with lateral tape movement so as to minimize the opportunity for micro-buckling. In one preferred embodiment, a portion of the guide flange is curved.
