Magnetic tape, magnetic tape cartridge, and magnetic recording and reproducing apparatus

Abstract

The magnetic tape includes a non-magnetic support; and a magnetic layer containing a ferromagnetic powder, in which, in a small-angle X-ray scattering spectrum obtained by small-angle X-ray scattering measurement of the non-magnetic support, in a region where a q-value is 0.01 to 0.10 Å−1, a ratio Imax/Imin of a scattering intensity Imax at a q-value qmax of a maximal value of a scattering intensity change rate to a scattering intensity Imin at a q-value qmin of a minimal value of the scattering intensity change rate is 2.7 or more, and qmin<qmax is satisfied, and a glass transition temperature Tg of the non-magnetic support is 140° C. or higher.
