Abstract
The magnetic tape includes a non-magnetic support, and a magnetic layer containing a ferromagnetic powder, in which an absolute value ΔN of a difference between a refractive index Nxy measured in an in-plane direction of the magnetic layer and a refractive index Nz measured in a thickness direction of the magnetic layer is 0.25 or more and 0.40 or less, and standard deviation a of the ΔN in a width direction of the magnetic layer is 0.05 or less.
