ABSTRACT:
The belt of a rectangular two-reel tape cartridge is stretchably entrained around the tape packs, a single belt-driving roller, and four idler rollers. Each idler roller is positioned near a corner of the cartridge so that the belt has an angle of wrap of at least 150 degrees at the periphery of each of the tape packs. Such angle of wrap permits the cartridge to employ magnetic recording tape that has a smoother backside and yet avoids read/write errors at high tape speeds.
