ABSTRACT:
The present invention provides novel magnetic recording media wherein the magnetic recording material is an alloy consisting essentially of a major amount of cobalt and either or both of a minor amount of a nonmagnetic element soluble in cobalt which reduces the face-centered cubic phase, or a minor amount of another element which increases the coercive force of the alloy by isolating grain boundaries. The presence of either or both of these additives increases the coercive force of the alloy with attendant improvement in digital recording performance.
