Benefits of technology

This solution enables precise identification and alignment of servo bands, preventing mispositioning and providing feedback during lateral repositioning, thereby enhancing the accuracy and reliability of data track access in linear data storage tape systems.

Problems solved by technology

Such extra sensors add cost to a tape drive, which is always undesirable, if the extra cost can be avoided.

Embodiment Construction

[0035] This invention is described in preferred embodiments in the following description with reference to the Figures, in which like numbers represent the same or similar elements. While this invention is described in terms of the best mode for achieving this invention's objectives, it will be appreciated by those skilled in the art that variations may be accomplished in view of these teachings without deviating from the spirit or scope of the invention.

[0036]FIGS. 1 and 2 illustrate a servo system and a linear data storage tape 10, the linear data storage tape having a plurality of separate longitudinal servo bands 11, 12, 13 and 14, which are laterally positioned on the linear data storage tape, and which are identifiable in accordance with the present invention. The example of FIG. 1 comprises a magnetic tape media with magnetically written servo bands, and with data tracks positioned between the servo bands. In magnetic tape media, a tape head 16 typically comprises a number o...

Abstract

In a tape having separate servo bands of patterns positioned laterally across the tape, the patterns of a separate servo band have at least one differentiating characteristic with respect to patterns of another of the separate servo bands. The differentiating characteristic allows identification of the separate servo bands. For example, the patterns of a separate servo band have differing azimuthal orientations of detectable transitions with respect to another servo band, such as being laterally inverted. In another, variations in the width of gaps of patterns are made with respect to another servo band. In another, variations are made in the number of the detectable transitions of patterns with respect to the patterns of another servo band.

Description

FIELD OF THE INVENTION [0001] This invention relates to separate longitudinal servo bands which are laterally positioned on a linear data storage tape, and, more particularly, to identification of the servo bands for independent addressability. BACKGROUND OF THE INVENTION [0002] Linear data storage tape comprises a medium for storing large amounts of data, and typically comprises a plurality of data tracks that extend longitudinally along the tape. A common example comprises magnetic tape media, and a less common example comprises optical tape media. A tape head is employed for reading and / or writing data on the data tracks, and is typically shared between various data tracks or groups of data tracks, and is moved between tracks or groups of tracks in the lateral direction of the tape. In magnetic tape media, the tape head typically comprises a number of separate elements which read and / or write data with respect to a number of parallel tracks, and is provided with one or more separ...
