Abstract
The magnetic tape includes a non-magnetic support, and a magnetic layer including a ferromagnetic powder. A dimension change amount Δw in a width direction with respect to a tension change in a longitudinal direction is 400 ppm/N to 900 ppm/N, the magnetic layer includes a plurality of servo bands, and a coefficient of variation CV calculated by Equation A: CV=(σG/Δw)×100 is 10% or less. The σG is a standard deviation of servo band intervals measured in a region of the magnetic tape over 100 m in the longitudinal direction with a tension of 0.6 N in the longitudinal direction. A magnetic tape container containing the magnetic tape.
