    • The object of the present is to provide high-quality magnetic recording media capable of easy tracking, and allowing high-density recording, high-speed recording, and higher capacity without increasing the write-current at magnetic heads. The nanohole structure comprises a metal or metal-compound base material and plural arrays of nanoholes, wherein the plural arrays of nanoholes are respectively arranged into regular alignments, the regular alignments are different between adjacent arrays, and the regular alignments are alternately disposed within the metal or metal-compound base material. The magnetic recording medium according to the present invention comprises a substrate, a porous layer into which plural nanoholes are formed, and a magnetic material within the plural nanoholes, wherein the plural nanoholes are formed in a direction approximately vertical to the plane of the substrate, the porous layer is a nanohole structure according to the present invention.
    • 本发明的目的是提供能够容易跟踪并且允许高密度记录,高速记录和更高容量的高质量磁记录介质,而不增加磁头的写入电流。 纳米孔结构包括金属或金属化合物基材和多个纳米孔阵列,其中纳米孔的多个阵列分别布置成规则对准,相邻阵列之间的规则对准不同,并且规则对准交替地设置在金属 或金属化合物基材。 根据本发明的磁记录介质包括基板,形成有多个纳米孔的多孔层和在多个纳米孔内的磁性材料,其中所述多个纳米孔在与基板的平面大致垂直的方向上形成, 多孔层是根据本发明的纳米孔结构。
