Abstract
The tape cartridge leader includes a smoothing feature that comprises a blind cut out formed in a surface of the tape cartridge leader that faces the hub of the take-up reel when the tape cartridge leader is wound on the hub to compensate for the irregularity generated by the buckling mechanism. The blind cut out consists of a shallow, smooth depression that is positioned to overlay the buckling mechanism. The geometry and size of the blind cut out can be selected from a wide variety of options, with all of these variations having the advantage of providing increased tensile strength for the tape cartridge leader over tape cartridge leaders that use smoothing apertures, since there is no hole formed in the tape cartridge leader.
