A magnetic tape includes: a non-magnetic support; a magnetic layer on one surface side of the non-magnetic support; and a back coating layer on the other surface side. The center line average surface roughness Ra measured regarding the surface of the magnetic layer is 1.0 nm to 1.8 nm. The magnetic layer includes ferromagnetic hexagonal ferrite powder and non-magnetic powder. The tilt cos θ of the ferromagnetic hexagonal ferrite powder with respect to a surface of the magnetic layer acquired by cross section observation performed using a scanning transmission electron microscope is 0.85 to 1.00. Further, the logarithmic decrement acquired by a pendulum viscoelasticity test performed regarding the surface of the back coating layer is less than or equal to 0.060.
