Abstract: Techniques are disclosed relating to sharing data. A first computer system may receive data shared by a second computer system to permit the first computer system to perform processing of the data according to a set of policies. The first computer system may instantiate a verification environment in which to process the shared data. The first computer system may process a portion of the shared data by executing a set of processing routines to generate a result based on the shared data. The verification environment may verify whether the result is in accordance with the set of policies. The verification environment may determine whether to output the result based on the verifying and may send an indication of an outcome of the determining to the second computer system. The indication may be usable to determine whether to provide the first computer system with continued access to the shared data.

Abstract: A heat-assisted magnetic recording (HAMR) medium has a heat-sink layer, a chemically-ordered FePt (or CoPt) alloy magnetic layer and a MgNiO intermediate layer between the heat-sink layer and the magnetic layer. The intermediate layer is a solid substitution crystalline alloy of the form (Mg(100-y)Niy)O, where y is less than 10 and greater than or equal to 0.5. The magnetic layer may be formed directly on the MgNiO intermediate layer, in which case the MgNiO intermediate layer functions as both a seed layer and a thermal barrier layer. The HAMR medium may also include an optional layer of crystalline “pure” MgO directly below or directly above the MgNiO intermediate layer. If the MgO layer is located directly above the MgNiO intermediate layer then the MgNiO intermediate layer functions primarily as a thermal barrier layer. The HAMR medium with the MgNiO intermediate layer provides a substantial improvement in corrosion resistance.

Abstract: Disclosed herein are embodiments of a heat-assisted magnetic recording (HAMR) device comprising a waveguide and a near-field transducer (NFT) coupled to the waveguide. The NFT comprises a core layer comprising an insulator, a first metal layer adjacent to the core layer, and a second layer adjacent to the first metal layer, wherein the second layer comprises a material that is substantially mechanically and thermally stable and thereby functions as a hard jacket to mitigate deformation of the NFT. The first metal layer may comprise a plasmonic metal, such as gold. The second layer may comprise tungsten, chromium, or a dielectric material.
