    摘要: Example embodiments may provide data storage devices using movement of a magnetic domain wall and/or a method of operating magnetic domain data storage devices. The data storage device may include a first magnetic layer for writing data having two magnetic domains magnetized in different directions, a second magnetic layer for storing data at a side of the first magnetic layer, a data recording device connected to the first magnetic layer and the second magnetic layer, and a plurality of reading heads configured to read the second magnetic layer. The data storage device may store a larger amount of data without requiring moving mechanical systems.

    摘要: A nano imprint master and a method of manufacturing the same are provided. The method includes: implanting conductive metal ions into a substrate including quartz to form a conductive layer inside the quartz substrate; coating a resist on the quartz substrate in which the conductive layer is formed, to form a resist coating layer; exposing the resist coating layer to an electron beam to form micropatterns; etching the quartz substrate by using the resist coating layer, in which the micropatterns are formed, as a mask; and removing the resist coating layer to obtain a master in which micropatterns are formed.
