<p>A method of making a magnetic recording medium includes sputtering a magnetic material containing iron onto a substrate (3) in an atmosphere of argon gas mixed with nitrogen gas to deposit a magnetic film on the substrate (3). The nitrogen is preferably present in an amount of 10 to 10000 ppm, and a preferred version of the method comprises jointly sputtering a rare earth metal and an iron-cobalt alloy. </p> |
