HOCHORIENTIERTE DÜNNE MAGNETISCHE FILME, AUFZEICHNUNGSTRÄGER, WANDLER, MIT DIESEN HERGESTELLTE VORRICHTUNGEN UND HERSTELLUNGSVERFAHREN |
摘要 |
The present invention provides for magnetic and magneto-optic recording media, transducers and data storage devices constructed therefrom that have highly oriented films having long range order in the crystal structure of the film. The recording medium includes a magnetic recording layer comprised of Co-based material, such as Co or one or more Co alloys having a (1010) crystal texture, a substrate, a first underlayer having an fcc structure and a (110) crystal texture disposed between the substrate and the magnetic recording layer. A second underlayer having a bcc structure and a (112) crystal texture is also disposed between the magnetic recording layer and the first underlayer. In particular, if a (110) Si single crystal substrate is non-oxidized certain metals having fcc structures, such as Ag Cu, Al, and Au and fcc derivative structures, such L10 and L12 structures, can be epitaxially grown on the Si surface. <IMAGE> |
