    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.
