ABSTRACT:
A magnetic recording medium having a magnetic thin film, wherein crystal grains constituting the magnetic thin film are separated by a crystal boundary region containing a non-ferromagnetic and non-metallic phase. The magnetic recording medium of the present invention provides a high coercivity and a remarkably reduced media noise property, and a high productivity in the mass production thereof.
