Abstract
Provided are a data storage device using magnetic domain wall movement and a method of operating the data storage device. The data storage device includes a first magnetic layer for writing data having two magnetic domains magnetized in opposite directions to each other and a second magnetic layer for storing data formed on at least one side of the first magnetic layer. The data storage device may further include a data recording device connected to both ends of the first magnetic layer and the end of the second magnetic layer which is not adjacent to the first magnetic layer, a read head formed a predetermined distance from the end of the second magnetic layer which is not adjacent to the first magnetic layer, and a current detector connected to the read head and the data recording device.
