    摘要: A magnetic track includes first and second magnetic domain regions having different lengths and different magnetic domain wall movement speeds. A longer of the first and second magnetic domain regions serves as an information read/write region. An information storage device includes a magnetic track. The magnetic track includes a plurality of magnetic domain regions and a magnetic domain wall region formed between neighboring magnetic domain regions. The plurality of magnetic domain regions includes a first magnetic domain region and at least one second magnetic domain region having a smaller length than the first magnetic domain region. The information storage device further includes a first unit configured to perform at least one of an information recording operation and an information reproducing operation on the first magnetic domain region, and a magnetic domain wall movement unit configured to move a magnetic domain wall of the magnetic domain wall region.

    摘要: Information storage devices and methods of manufacturing the same are provided. An information storage device includes a magnetic layer formed on an underlayer. The underlayer has at least one first region and at least one second region. The first and second regions have different crystallinity characteristics. The magnetic layer has at least one third region formed on the at least one first region and at least one fourth region formed on the at least one second region. The third and fourth regions have different magnetic anisotropic energy constants.
