1. A magnetic tape comprising:
a non-magnetic support; and
a magnetic layer including a ferromagnetic powder,
wherein 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,
a coefficient of variation CV calculated by Equation A:
CV=(σG/Δw)×100
is 10% or less, and
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.
