[Solving Means] A tape-shaped magnetic recording medium includes: a base; and a magnetic layer that is provided on the base and includes a magnetic powder. The magnetic powder includes magnetic particles that have a uniaxial crystal magnetic anisotropy and contain cobalt ferrite. A ratio L4/L2 of a component L4 having a multiaxial crystal magnetic anisotropy to a component L2 having a uniaxial crystal magnetic anisotropy is 0 or more and 0.25 or less, the components being obtained by applying Fourier transformation to a torque waveform of the magnetic recording medium.
