1. A magnetic tape cartridge comprising:
a magnetic tape in which a plurality of servo patterns are recorded along a longitudinal direction; and
a storage medium that is configured to store servo format information including servo pattern inclination information which is information on an inclination of the servo pattern with respect to a first imaginary straight line,
wherein the first imaginary straight line is a straight line along a width direction of the magnetic tape,
the servo pattern is at least one linear magnetization region pair,
the linear magnetization region pair includes a first linear magnetization region which is linearly magnetized, and a second linear magnetization region which is linearly magnetized,
the first linear magnetization region and the second linear magnetization region are inclined in opposite directions with respect to the first imaginary straight line,
the first linear magnetization region has a steeper inclined angle with respect to the first imaginary straight line than the second linear magnetization region, and
the servo pattern inclination information includes information on the inclined angle of the first linear magnetization region with respect to the first imaginary straight line, and information on an inclined angle of the second linear magnetization region with respect to the first imaginary straight line.
