    摘要： A data storage medium is provided according to the present invention for magnetic recording. The data storage medium includes a substrate having a locking pattern etched therein defining patterned regions. The patterned regions are chemically modified by depositing a self-assembled monolayer therein. A first layer of nanoparticles is provided in the patterned regions on top of the self-assembled monolayer and is chemically bonded to the substrate via the self-assembled monolayer. The first layer of nanoparticles is chemically modified using functional surfactant molecules applied thereto, such that a second layer of nanoparticles may be formed on top of the first layer and chemically bonded thereto via the functional surfactant molecules. Additional layers of nanoparticles may be applied by chemically modifying the top layer of nanoparticles utilizing the functional surfactant molecules and applying a further layer of nanoparticles thereto.

    摘要： A thin film structure, such as a magnetic recording media, having a magnetic layer and a stress-effecting layer is disclosed. The stress-effecting layer induces a magneto-elastic anisotropy in the magnetic layer. The stress-effecting layer can be activated by the application of an external stress and/or strain. The induced magneto-elastic anisotropy can transiently achieve and/or enhance a tilt angle of the medium. The medium can be a perpendicular magnetic recording medium, a longitudinal magnetic recording medium and/or a tilted magnetic recording medium. The magnetic recording media is suitable for use with a data storage system, such as a HAMR data storage system.

    摘要： A magnetic recording medium with domain wall pinning sites including a substrate, a soft magnetic underlayer, and a magnetic recording layer overlying the soft magnetic underlayer. In one embodiment the magnetic recording layer has at least two grooves providing a track having first and second sidewalls formed by the grooves. The sidewalls provide a plurality of pinning sites formed between the sidewalls for pinning magnetic domain walls in the track. At least one of the pinning sites includes a first indentation in the first sidewall and a paired second indentation in the second sidewall. In one embodiment data can be stored within the magnetic recording layer by positioning a write head adjacent the track and inducing at least two magnetic domains defining a domain wall. The domain wall migrates to one of the pinning sites in the track.

    摘要： The present invention is a planar spiral inductor a top magnetic layer a bottom magnetic layer; and a plurality of conductive coils disposed between said top magnetic layer and said bottom magnetic layer. A significant difference from prior art is that the top and bottom magnetic layers have their centers effectively cut out using lithographic techniques or other techniques to frame the core of the conductive spirals. An advantage of this structure over the prior art is that when magnetic anisotropies other than shape are kept small, then the magnetic configuration will produce a magnetostatic shape anisotropy such that the easy axis (low energy direction of magnetization) lies parallel to the legs of a rectangular frame or the circumference of a circular frame, as will be described. During operation of the inductor, the field produced by the coils flows in a radial direction and will be perpendicular to the easy axis direction thereby causing magnetization reversal to occur by rotation while advantageously utilizing the full structure in this mode.

    摘要： The invention is embodied in an anisotropic, soft magnetic thin film article comprising a cobalt-iron-chromium-nitrogen (Co--Fe--Cr--N) alloy. The thin film is formed such that the alloy has a relatively high saturation magnetization (4.pi.M.sub.s), e.g., greater than approximately 8 kilogauss (kG), a relatively low coercivity (H.sub.c), e.g., less than approximately 2.0 oersteds (Oe), a relatively high squareness ratio (M.sub.r /M.sub.s), e.g., greater than approximately 0.90, and a relatively high anisotropy field (H.sub.k), e.g., greater than approximately 20 Oe, in an as-deposited condition or, alternatively, with a relatively low temperature treatment, e.g., below approximately 300.degree. Celsius. The inventive films are suitable for use in electromagnetic devices, e.g., in microtransformer cores, inductor cores and in magnetic read-write heads.
