Thin-film medium with compositional gradient |
摘要 |
A magnetic thin-film media with high coercivity and low noise characteristics is disclosed. The medium has a gradient-composition thin-film magnetic layer in which a lowermost stratum is composed of a first alloy, preferably, having relatively low noise and low magnetic remanence characteristics, and an uppermost stratum composed of a second alloy having relatively high noise and high magnetic remanence characteristics. The medium is characterized by a coercivity which is substantially greater, and a media noise which is substantially less than that of a similar medium whose magnetic thin-film layer is composed of either the first or second alloy alone. Also disclosed is a method of producing such a medium.
