    摘要: A storage device includes a storage medium, a controller and a read/write head. The storage medium includes a substrate with a plurality of nano-structures arranged in an ordered pattern on a surface of the substrate. The controller is coupled to the storage medium. The controller has a read structure that extends over the substrate and a positioner adapted to adjust a position of the read structure relative to the substrate. The read/write head is mounted on the read structure and positioned over the substrate during operation. The read/write head is adapted to read and to write information to and from the plurality of nano-structures.

    摘要: A method of fabricating a magnetic storage medium comprises: forming an underlayer on a heat sink layer; co-sputtering a magnetic material and a thermally insulating nonmagnetic material to form a recording layer on the underlayer, wherein the recording layer includes grains of the magnetic material in a matrix of the thermally insulating nonmagnetic material; and heating the recording layer to align an easy axis of magnetization of the magnetic material in a direction perpendicular to the underlayer. A magnetic storage medium fabricated using the method is also provided.

    摘要: A bit patterned magnetic recording medium for use in HAMR, which is optimized for optical coupling efficiencies and improved magnetic read-back coupling. The medium comprises bit-patterned magnetic recording elements, each corresponding to a magnetic data bit, and each comprising a cluster of discrete and separated magnetic grains. The desired packing fraction may be obtained by defining the number of grains within a bit, while bit-patterning provides efficient optical transmission. The grains have an effective packing fraction that enhances magnetic read-back signals, and the bits are distributed in a pattern having a packing fraction that enhances the optical coupling efficiency. The bits and/or the grains may be substantially thermally and optically isolated.
