摘要： 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.

摘要： A magnetic head assembly in a linear tape system. The magnetic head assembly includes a magnetic head having a central section, a first outrigger, and a second outrigger. The central section maintains at least one read/write element. The first outrigger is positioned adjacent the central section and forms at least one air bleed slot. The second outrigger is positioned adjacent the central section opposite the first outrigger and also forms at least one air bleed slot. Finally, the central section is laterally moveable relative to the outriggers. With this configuration, the moveable, central section, otherwise used for lateral positioning of the read/write element relative to a magnetic tape, is separated from the outriggers that otherwise minimize a fly height between the magnetic tape and the outriggers.

摘要： In general, the invention is directed to techniques for reducing deformation of tape in data tape cartridges during storage to promote dimensional stability and increased tape longevity. The techniques involve controlling the winding tension applied to a tape during a final winding pass prior to unloading a data tape cartridge containing the tape from a drive. Excessive winding tensions can produce strain and compression on a tape pack, causing the tape to deform over time. Applications of reduced winding tension during the final pass provide reduced tape pack tension during periods in which the data tape cartridge is not used.

摘要： A data storage tape cartridge including a housing, first and second tape reels, a storage tape, first and second corner guides and an idler wrap guide. The housing defines a head access window. The tape reels are rotatably disposed within the housing, with the storage tape extending between the tape reels. The first and second comer guides are disposed within the housing at opposite sides of the head access window. Finally, the idler wrap guide is disposed within the housing and defines a tape path extending from the first tape reel to the idler wrap guide, and from the idler wrap guide to the first corner guide. The idler wrap guide is configured to frictionally dampen lateral movement of the storage tape upon rotation of the tape reels to greatly reduce servo off track events.

摘要： Magnetic storage tape and techniques for erasing and writing to magnetic storage tape having a perpendicular squareness greater than 50 percent and a longitudinal squareness less than 50 percent are described. In general, the magnetic tape may be biased with a remanence magnetization, or magnetic orientation, in any direction. One or two head systems may use various magnetic field patterns to create the desired remanence magnetization. Servo marks may have a remanence magnetization in an opposite magnetic orientation than that of the remaining bias on the servo track, e.g., substantially perpendicular to the magnetic tape. In some examples, a write head may alternate the direction of the magnetic field to continuously bias and write servo patterns to the magnetic tape. In addition, a symmetrical servo mark may be created in the magnetic tape with a write head having a gap width approximately equal to the length of the servo mark.

摘要： The invention is directed to a data storage medium that includes a plurality of servo bands distributed across the data storage medium and a plurality of data tracks positioned between each of the plurality of distributed servo bands. The data storage medium comprises a servo band pitch of less than 200 micrometers. The large number of servo bands distributed across the data storage medium with a relatively small servo band pitch reduces the influence of media dimensional instability. In this way, the invention may substantially increase data read head positioning accuracy, especially in the case of narrow track widths. A read head array arranged in a two-dimensional matrix that includes a first servo read head, a second servo read head, and a plurality of data read heads positioned between the first and second servo read heads may be applied to a data storage medium as described herein.

摘要： The invention is directed to techniques for erasing data storage tape for reuse. In an embodiment, an erase head module for erasing data storage tape comprises a set of erase gaps and one or more servo read elements. The set of erase gaps is configured to coincide with data bands of the data storage tape to allow erasure of only the data bands of the data storage tape while not erasing servo bands of the data storage tape. The one or more servo read elements detect one of the servo bands of the data storage tape when the set of erase gaps are proximate the data bands of the data storage tape to allow the erase head module to accurately track the data bands with the set of erase gaps.

摘要： The invention is directed to techniques for storing information on a linear data storage medium, such as magnetic tape. According to the invention, a write head array concurrently writes a plurality of data tracks and at least one servo track onto the magnetic tape. In this way, the servo track is integrated between the data tracks. The servo track may, for instance, be located in the middle of a data band, and may span a distance corresponding to two data tracks. By concurrently writing the servo track with the data tracks, track misregistration (TMR) can be reduced or eliminated during the write operation.
