Magnetic recording medium having a recording layer with a diffraction peak of magnetic atoms |
摘要 |
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°. |

1. A magnetic recording medium comprising:
a base material which has flexibility; a lower coating layer; and a recording layer, wherein, 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 from 5° to 10°, wherein an arithmetic average roughness Ra of an interface between the base material and a lower layer of the lower coating layer is from 0.4 nm to 1.0 nm. |
