The present invention relates to a
magnetic tape cassette, a
magnetic tape drive, a
magnetic tape system, and an operating method of the magnetic
tape drive. In the magnetic tape cassette, there is provided a housing for accommodating a magnetic tape having a plurality of
servo bands formed thereon, and a storage medium disposed in the housing. The plurality of
servo bands are formed along the entire length of the magnetic tape at positions spaced apart in the width direction of the magnetic tape. The storage medium stores
pitch information capable of determining the spacing between the plurality of
servo bands in the width direction, and distance information capable of determining the distance between a plurality of servo reading elements that read the plurality of servo bands.
