Oriented magnetic recording media on a nonmetallic substrate |
摘要 |
This invention provides a disk which has an in-plane oriented magnetic recording layer on a glass, ceramic, or other nonmetallic substrate and a method for making the disk. A thin layer of texturable NiP is sputtered on the substrate. This NiP layer is textured before the magnetic layer is deposited. The disk combines all the advantages of a glass or ceramic substrate along with the advantages of an oriented magnetic medium.
