ABSTRACT:
The coaxial reel tape cartridge uses a lengthy tape path within the tape cartridge to reduce the stresses on the tape medium as it is transported between the two reels. The tape is drawn from each reel around a corresponding rotating guide element which is coplanar with the tape reel. The tape is then transported along one side of the tape cartridge exterior housing to a corresponding hydrostatic bearing which is located at a corner of the tape cartridge adjacent the tape access opening. The hydrostatic bearing is coplanar with the tape guide, but at a slight angle with the vertical to thereby impart a slight twist to the tape as it traverses the length of the tape cartridge. The two hydrostatic bearings are located inside of and at opposite ends of the tape cartridge exterior housing, flanking the tape access opening. The two hydrostatic bearings are attached to a base plate which maintains the hydrostatic bearings coplanar with respect to each other. The base plate itself is angled with respect to the horizontal plane of the tape cartridge exterior housing so that the tape, as it traverses the path between the two hydrostatic bearings, changes elevation from the plane of the first reel to the plane of the second reel. The tape is only subjected to a twist along one segment of the tape path while remaining coplanar along this segment of the tape path, and is subjected to an elevation change in a manner that involves neither twist nor bending.
