MAGNETIC DATA STORAGE DISK WITH LOW INTRINSIC MEDIA NOISE |
| 摘要 |
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. |
