Abstract

A magnetic recording medium includes a base material which has flexibility, a lower coating layer, and a recording layer, in which, in X-ray diffraction peaks, a value of Δθ50 where a diffraction peak of magnetic atoms which are included in the recording layer is measured by a locking curve method is 5° or more to less than 10°.
