ABSTRACT:
A manufacturing process of Co-Ni magnetic recording media by sputtering Co-Ni thin film layer on a substrate in Argon atomsphere including nitrogen and heating the thin film to evaporate nitrogen from the thin film to prepare the magnetic recording media appropriate for high density longitudinal recording, wherein on sputtering the substrate is maintained at a temperature of room temperature to 300.degree. C.
