Abstract
A magnetic tape cartridge includes a magnetic tape wound around a reel, in which the magnetic tape has a first region, which is a predetermined region influenced by a width change of the magnetic tape accompanied by deformation of the reel due to winding of the magnetic tape, and a second region, which is a region on an outer peripheral side of the reel with respect to the first region, and regarding a degree of elongation in a longitudinal direction of the magnetic tape, the degree of the first region is equal to or larger than the degree of the second region.

A magnetic tape cartridge comprising:
- a magnetic tape wound around a reel,
- wherein the magnetic tape has a first region, which is a predetermined region influenced by a width change of the magnetic tape accompanied by deformation of the reel due to winding of the magnetic tape, and a second region, which is a region on an outer peripheral side of the reel with respect to the first region, and
- regarding a degree of elongation in a longitudinal direction of the magnetic tape, the degree of elongation of the first region is larger than the degree of elongation of the second region,
- wherein regarding a tension in the magnetic tape wound around the reel, the tension decreases from an inner side toward an outer side of the reel, and a decrease rate of the tension at the first region of the magnetic tape is larger than a decrease rate of the tension at the second region of the magnetic tape, such that the degree of elongation of the first region of the magnetic tape is larger than the degree of elongation of the second region of the magnetic tape.
