| Abstract: | We discuss current media construction-new media structures .and techniques for evaluating media performance.and discuss the development of future media for hard disk. It is pointed out that high recording areal density of hard disk requires very high coercivities of the media and extremly small magnetic recording domain to satisfy the high signal-to-noise ratio requirements. |

| Keywords: | hard disk magnetic recording media recording areal density film .sputtering |
