  • Publication number: 20120275058
    Abstract: According to one embodiment, a magnetic recording medium includes a substrate, an auxiliary layer formed on the substrate, and at least one perpendicular magnetic recording layer formed on the auxiliary layer. The perpendicular magnetic recording layer includes a magnetic dot pattern. The perpendicular magnetic recording layer is made of an alloy material containing one element selected from iron and cobalt, and one element selected from platinum and palladium. This alloy material has the L10 structure, and is (001)-oriented. The auxiliary layer includes a dot-like first region covered with the magnetic dot pattern, and a second region not covered with the magnetic dot pattern. The first region is made of a (100)-oriented nickel oxide. The second region contains nickel used in the first region as a main component.

    Abstract: Method and apparatus for logging of data within a data storage system, such as a tape drive library. The tape drive library includes a central storage (memory) providing storage space assigned to each tape drive in the tape drive library and allowing each tape drive to directly store data there, that is to log data files. The logging of the data files is at the instigation of each tape drive and not via polling, so as to perform logging synchronous with tape drive events. In one version, the tape drives are coupled to the central storage via an Ethernet network and the log files conform to a standard file protocol, such as a network file system.
