ELECTRICALLY CONDUCTIVE UNDERLAYER TO GROW FEPT GRANULAR MEDIA WITH (001) TEXTURE ON GLASS SUBSTRATES |
| 摘要 |
A perpendicular magnetic recording medium, comprising: a substrate; a buffer layer deposited in a first orientation on top of the substrate; an underlayer deposited in a second orientation on top of the buffer layer, the underlayer comprising an electrically conductive oxide; and a magnetic recording layer deposited on top of the underlayer and having an axis of magnetic anisotropy substantially perpendicular to the surface thereof. |

1. A perpendicular magnetic recording medium, comprising:
a substrate; a buffer layer deposited in a first orientation on top of the substrate; an underlayer deposited in a second orientation on top of the buffer layer, the underlayer comprising an electrically conductive oxide of Mg with one or more of Ti, Zr and Hf, the oxide comprising between 5 and 35 atomic percent Mg; and a magnetic recording layer deposited on top of the underlayer and having an axis of magnetic anisotropy substantially perpendicular to the surface thereof. |
