    摘要: Information storage devices and methods of manufacturing the same are provided. A magnetic track of the information storage device includes a magnetic layer in which at least one magnetic domain forming region and at least one magnetic domain wall forming region are alternately disposed in a lengthwise direction. The at least one magnetic domain forming regions has a different magnetic anisotropic energy relative to the at least one magnetic domain wall forming region. An intermediate layer is formed under the magnetic layer. The intermediate layer includes at least one first material region and at least one second material region. Each of the at least one first material regions and the at least one second material regions corresponds to one of the at least one magnetic domain forming regions and the at least one magnetic domain wall forming regions.

    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.
