ABSTRACT:
In manufacturing a magnetic recording medium, a flow of iron vapor is formed in a nitrogen atmosphere and iron vapor particles in the flow of iron vapor are deposited on a non-magnetic substrate together with nitrogen particles to form an iron nitride film thereon. Before deposition on the non-magnetic substrate, the nitrogen particles are ionized by an ion beam generating means and the iron vapor particles are ionized by a high-frequency discharge.
