Abstract
Provided are information storage devices using movement of magnetic domain walls and methods of operating information storage devices. An information storage device includes a magnetic track and an operating unit. The magnetic track includes a plurality of magnetic domains separated by magnetic domain walls. The size of the operating unit is sufficient to cover at least two adjacent magnetic domains. And, the operating unit may be configured to write/read information to/from a single magnetic domain as well as a plurality of magnetic domains of the magnetic track.
