Thin film metal alloy magnetic recording disk. |
| 摘要 |
<p>An improved CoPt alloy magnetic recording disk for horizontal recording has a magnetic recording layer which includes oxygen, the oxygen being present preferably in the range of approximately 5 to 30 atomic percent. The resulting disk structure has substantially decreased intrinsic media noise at high linear recording density.</p> |
