PROBLEM TO BE SOLVED: To obtain a magnetic recording medium having excellent durability and head touch by forming an iron nitride ferromagnetic film on a base body in such a manner that when the film is measured by X-ray diffraction and electron diffraction, only halo is recognized. SOLUTION: This magnetic recording medium is produced by forming an iron nitride ferromagnetic film on a base body. The ferromagnetic film has such properties that any peak which indicates a crystal plane is not detected by a measuring means such as X-ray diffraction and electron diffraction but only halo is observed, or, even in the case of a magnetic recording medium having an iron carbide ferromagnetic film on a base body or having an iron nitride carbide ferromagnetic film on a base body, only halo is observed by a measuring means of X-ray diffraction and electron diffraction in the iron carbide-based ferromagnetic film or iron nitride carbide-based ferromagnetic film. |
