    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. 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： An information storage device includes a magnetic track and a magnetic domain wall moving unit. The magnetic track has a plurality of magnetic domains and a magnetic domain wall between each pair of adjacent magnetic domains. The magnetic domain wall moving unit is configured to move at least the magnetic domain wall. The information storage device further includes a magneto-resistive device configured to read information recorded on the magnetic track. The magneto-resistive device includes a pinned layer, a free layer and a separation layer arranged there between. The pinned layer has a fixed magnetization direction. The free layer is disposed between the pinned layer and the magnetic track, and has a magnetization easy axis, which is non-parallel to the magnetization direction of the pinned layer.
