Magnetic data storage disk with low intrinsic media noise

An improved CoPt based or CoNi based alloy magnetic data storage disk has a magnetic recording layer which is a laminated structure of relatively thin magnetic alloy films separated by relatively thin non-magnetic spacer films. The resulting laminated disk structure has substantially decreased intri...

More Information
Summary:An improved CoPt based or CoNi based alloy magnetic data storage disk has a magnetic recording layer which is a laminated structure of relatively thin magnetic alloy films separated by relatively thin non-magnetic spacer films. The resulting laminated disk structure has substantially decreased intrinsic media noise at high linear recording densities.
