Magnetic tape cartridge, magnetic tape drive, magnetic tape system, and method of operating magnetic tape drive

A magnetic tape system comprising:

• a cartridge including:
• a case in which a magnetic tape is accommodated;
• and
• a storage medium provided in the case,
• wherein the storage medium stores tilt feature information over an entire length of the magnetic tape at preset intervals, a preset interval being a predetermined length,
• wherein the tilt feature information is information about a plurality of magnetic elements that perform at least one of reading from the magnetic tape or writing of data on the magnetic tape, the information indicating a feature of a disposition direction of the plurality of magnetic elements with respect to a width direction of the magnetic tape,
• the system further including a tension controller,
• wherein the tilt feature information is adjusted by tension information of the magnetic tape at the preset intervals, the tension information determined by the tension controller,
• in a case in which the tension information is greater than a preset upper limit value of an allowable range, the tilt feature information is adjusted by using a difference between the tension information and the preset upper limit value, and
• in a case in which the tension information is smaller than a preset lower limit value of the allowable range, the tilt feature information is adjusted by using a difference between the tension information and the preset lower limit value.
