ABSTRACT:
A tape bearing surface for a tape that reduces tape surface contact near the edge, while minimizing variation in cross-web tension, and a method of making the same. The tape surface piece has a longitudinal axes defining a tape path and a lateral axis is perpendicular to the longitudinal axis along a top surface. The top surface defines a convex shape having at least one distinct radii extending along the lateral axis. In one embodiment, the convex shape is elliptical or parabolic. In one embodiment, two distinct radii are formed so that a first radius proximate a center of the lateral axis is greater then a second radius proximate edges of the lateral axis. The present invention is also directed to a tape guide and a tape cartridge containing the present tape bearing surface.
