Magnetic tracks, information storage devices using magnetic domain wall movement, and methods of manufacturing the same

A method of manufacturing a magnetic track for an information storage device, the magnetic track including an intermediate layer arranged on a substrate, and a magnetic layer on the intermediate layer in a lengthwise direction, the method comprising:

• forming a seed layer on a substrate;
• forming the intermediate layer on the seed layer, the intermediate layer including at least one first material region and at least one second material region arranged alternately, the at least one first material region and the at least one second material region are different materials;
• and
• forming the magnetic layer on the intermediate layer, the magnetic layer including at least one magnetic domain forming region and at least one magnetic domain wall forming region arranged alternately in the lengthwise direction on the intermediate layer;
• wherein
• the magnetic track includes a plurality of magnetic domains and a plurality of magnetic domain walls arranged alternately in the lengthwise direction, and the plurality of magnetic domain walls are movable within the magnetic track in the lengthwise direction in response to at least one of an applied current and an applied magnetic field.
