<p>PROBLEM TO BE SOLVED: To provide a guide assembly for reducing undesired movement of a storage tape during use in a tape drive. SOLUTION: A tape drive is provided with the guide assembly including a first roller (30A) having a perimeter surface (56), a circumference (62), a longitudinal axis (50) and one or more of spaced apart, discontinuous grooves (32). The grooves (32) are disposed into the perimeter surface (56), with each groove (32) having a groove length (74) of less than the circumference (62) of the first roller (30A), for venting air between a storage tape and the first roller (30A) in order to inhibit lateral tape motion and directional continuity shift. Further, the grooves (32) can be semi-randomly distributed over the perimeter surface (56), thereby decreasing the incidence of print through.</p> |
