    摘要： A SiON overcoat for use on magnetic media for magnetic recording. The SiON overcoat is deposited by pulsed DC sputtering while applying a negative DC bias. The SiON overcoat is especially useful on perpendicular magnetic recording media because of its ability to deposit thinly and evenly on a rough, granular high coercivity recording media while maintaining excellent corrosion protection properties. A SiON overcoat can be applied less than 3 nm thick while still maintaining excellent mechanical and corrosion protection. The overcoat also has a very high density and water contact angle.

    摘要： A perpendicular magnetic recording medium has a multilayer recording layer (RL) structure that includes a ferromagnetic intergranular exchange enhancement layer for mediating intergranular exchange coupling in the other ferromagnetic layers in the RL structure. The RL structure may be a multilayer of a first ferromagnetic layer (MAG1) of granular polycrystalline Co alloy with Ta-oxide, a second ferromagnetic layer (MAG2) of granular polycrystalline Co alloy with Si-oxide, and an oxide-free CoCr capping layer on top of and in contact with MAG2 for mediating intergranular exchange coupling in MAG1 and MAG2. The RL structure may also be a multilayer of an intergranular exchange enhancement interlayer (IL) in between two ferromagnetic layers, MAG1 and MAG2, each with reduced or no intergranular exchange coupling. Because the IL is in direct contact with both MAG1 and MAG2, it directly mediates intergranular exchange coupling in each of MAG1 and MAG2.

    摘要： A perpendicular magnetic recording disk has an improved recording layer of a granular CoPtCr-based ferromagnetic alloy with inter-granular material made up of one or more oxides of Cr and one or more oxides of one or more of a segregant of Si, Ta, Ti, B, Nb or Hf, wherein the amount of oxygen present in the recording layer is greater than about 22 atomic percent and less than about 35 atomic percent. The amount of oxygen in the recording layer is substantially greater than the amount required for the stoichiometric oxide or oxides of the segregant or segregants, and a substantial portion of the oxygen present in the recording layer is present in the inter-granular material. The recording layer exhibits high signal-to-noise ratio (SNR), a coercivity Hc greater than about 5000 Oe and a nucleation field Hn greater (more negative) than about −1500 Oe.

    摘要： The disclosure claims a method for measuring throughput and a Maintenance End Point (MEP). The method is applied in the Multi-Protocol Label Switching-Transport Profile (MPLS-TP) network. The method comprises the following steps: a first MEP in the MPLS-TP network performs the transmission of the data packets with a second MEP in the MPLS-TP network in a preset time period; after the preset time period, the first MEP receives measurement information fed back by the second MEP, wherein the measurement information indicates the number of data packets transmitted by the second MEP in this transmission; according to the measurement information, the first MEP judges that packet loss does not occur in this transmission of the data packets and the transmission rate meets the requirement of target precision, and then obtains the throughput of the transmission of the data packets in the transmission direction. According to the technical solutions provided by the disclosure, measurement cost can be saved and operation and maintenance can be simplified.
