An object of the present invention is to provide a magnetic recording cartridge capable of correcting a width of a magnetic recording medium in a longitudinal direction thereof by adjusting running tension of a tape system or changing a winding direction even when stored in a high-temperature environment.

A magnetic recording cartridge including: a magnetic recording medium having a base layer; and a reel, in which a loss modulus at 65? C. of the base layer is 0.40 GPa or less, the magnetic recording medium is wound around the reel, and when a variation in width is measured over an entire length of the magnetic recording medium after storage at 65? C. for 360 hours, a sign of variation in width ?out on an outer side of winding is different from a sign of variation in width ?in on an inner side of winding, and the variation in width is 0 ppm at any position of two portions sandwiching a center line of the entire length of the magnetic recording medium in a case where the entire length of the magnetic recording medium is divided into four portions by dividing into four equal parts.

Provided is a magnetic tape cartridge including: a case in which a magnetic tape on which a plurality of servo bands are formed is accommodated; and a storage medium provided in the case, in which the plurality of servo bands are formed at positions spaced apart from each other in a width direction of the magnetic tape along an entire length direction of the magnetic tape, and the storage medium stores pitch information capable of specifying a pitch in the width direction between the plurality of servo bands and distance information capable of specifying a distance between a plurality of servo reading elements that have read the plurality of servo bands.

A magnetic tape cartridge includes a case in which a magnetic tape is accommodated and a storage medium provided in the case. At least one of reading or writing of data is performed by a plurality of magnetic elements, which are linearly disposed, with respect to the magnetic tape pulled out from the case. A disposition direction of the plurality of magnetic elements is tilted toward an entire length direction side of the magnetic tape with respect to a width direction of the magnetic tape. The storage medium stores tilt feature information indicating a feature of tilt of the disposition direction with respect to the width direction.
