MAGNETISCHES AUFZEICHNUNGSMEDIUM |
摘要 |
A magnetic recording medium employing the ferromagnetic film as the magnetic layer is disclosed in which the non-magnetic metal and/or the non-magnetic metal oxide are diffused into the ferromagnetic film along the direction of film thickness so that the concentration distribution will become substantially uniform. The magnetic recording medium has a high rectangular ratio and a low dispersion of the coercive force. |
