    摘要: A tilted magnetic recording medium comprises a layer of magnetic material having a magnetic easy axis defined by tilted alignment of a particular crystalline phase of the magnetic material. A film of (101) and (011) textured L10 phase of a tetragonal crystalline magnetic material has crystalline c-axes oriented 45° to the medium surface normal. The L10 crystalline magnetic alloy comprises a first element selected from the group consisting of Co and Fe, and a second element selected from the group consisting of Pt and Pd. A seedlayer comprising a bcc or B2 crystal structure with a natural texture of (110) creates interfacial stress with the magnetic layer, giving rise to a pure (101) and (011) textured L10 crystalline film. A textured underlying surface facilitates preferential formation of the seedlayer and subsequent growth of the magnetic material to achieve tilted magnetic directions perpendicular to the recording tracks.

    摘要: A data storage medium for perpendicular recording has a substrate and a ferromagnetic layer on the substrate for storing data bits. The ferromagnetic layer has a plurality of elongate grains of magnetizable material extending perpendicular to the substrate which form magnetic domains representative of data. Each magnetic domain is separated from adjacent magnetic domains by a bit edge domain wall region. Each elongate grain has a perpendicular height that is greater than a width of the bit edge domain wall region.

    摘要: The invention includes improving or enhancing exchange coupling within a thin film layer. The improvement or enhancement to the exchange coupling occurs between the grains that are deposited to form the thin film. The improvement or enhancement to the exchange coupling between the grains of the thin film results from annealing the thin film at an elevated temperature for a period of time. A thin film structure and/or a magnetic recording layer made in accordance with the invention are disclosed.
