| Research Abstract |
In order to realize the scanning multiprobe data storage system based on conductivity change, the recording media using conductivity-switching polymer architected in nanometer or molecular level was researched in this study. Rewritable recording on high-density patterned media fabricated by diblock copolymer lithography was successfully demonstrated. The fabrication process of ultra-flat metal surface with the flatness of angstrom level on large area also succeeded to be developed. In addition, it was succeeded that the conductivity of the aromatic polyimide film, which was formed by molecular layer deposition, was increased more than 500 times by applying pulsed voltages using a scanning probe microscope. Thus, it was demonstrated that the recording principle of this study has the potential to realize ultra-high density data storage and high signal/noise ratio.
