    • Provided is a perpendicular magnetic recording medium. The perpendicular magnetic recording medium includes: a substrate; a plurality of soft magnetic layers including a lower soft magnetic layer and an upper soft magnetic layer which are sequentially stacked on the substrate, wherein the upper soft magnetic layer has an anisotropic field greater than that of the lower soft magnetic layer; an isolating layer interposed between the lower and upper soft magnetic layers and preventing magnetic interaction between the lower and upper soft magnetic layers; an underlayer formed on the plurality of soft magnetic layers; and a recording layer formed on the underlayer and including a plurality of ferromagnetic layers each layer of which has a magnetic anisotropic energy which decreases as distance increases from the underlayer.
    • 提供了一种垂直磁记录介质。 垂直磁记录介质包括:基板; 多个软磁层,包括顺序堆叠在基板上的下软磁层和上软磁层,其中上软磁层的各向异性磁场大于下软磁层的各向异性磁场; 插入在所述下软磁层和所述软磁性层之间的隔离层,并防止所述下软磁层和所述软磁性层之间的磁相互作用; 形成在所述多个软磁性层上的底层; 以及形成在所述底层上并且包括多个铁磁层的记录层,每个铁磁层具有随距离从所述底层距离增加而减小的磁各向异性能量。

    • Provided are a magnetic recording medium and a method of manufacturing the magnetic recording medium. The magnetic recording medium includes a substrate, a soft magnetic underlayer formed on the substrate, a texturing layer formed on the soft magnetic underlayer and including a uniform pattern, and a recording layer including magnetic grains and a non-magnetic boundary region isolating the magnetic grains. The magnetic grains and the non-magnetic boundary region of the recording layer are formed into a regular granular structure by segregation according to the regular pattern of the texturing layer. Therefore, a regular granular structure can be formed in the recording layer without a process such as etching of the recording layer, so that the recording density of the magnetic recording medium can be largely improved.
    • 提供磁记录介质和制造磁记录介质的方法。 磁记录介质包括基板,形成在基板上的软磁性底层,形成在软磁性底层上的包含均匀图案的纹理层,以及包括磁性颗粒和磁性颗粒隔离的非磁性边界区域的记录层 。 根据纹理层的规则图案,记录层的磁性颗粒和非磁性边界区域通过偏析形成规则的颗粒结构。 因此,可以在记录层中形成规则的颗粒结构,而不需要诸如蚀刻记录层的处理,从而可以大大提高磁记录介质的记录密度。
