Recording medium that can be magnetized vertically and method for manufacturing same |
| abstract |
A recording medium which can be magnetized vertically contains a plate-shaped carrier body of nonmagnetic material of which at least one flat side is provided with a thin nonmagnetic intermediate layer having a very smooth surface, to which at least one magnetic recording layer of a material is applied, the axis of easy magnetization of which points in a direction perpendicular to the surface of the medium. The surface of this intermediate layer should be capable of being made smooth in a relatively simple manner. The intermediate layer comprises a glass plate, preferably of fused silica or silicate glass, which is cemented to the carrier body. For the carrier body, particularly a high-strength hardened Al-alloy can be used. |
