ABSTRACT:
The present invention provides a recording medium employing conductive polymers and a recording method employing the recording medium. The recording medium of the present invention is comprised of a substrate and a conductive polymer layer including a dopant therein and layered on the substrate. In addition, the recording method according to the present invention is effected on the basis of selective change in the amount of the dopant contained in the conductive polymers. The recording medium according to the present invention is utilizable ion the field of recording, memory and electronic devices, while displaying remarkably advantageous recording characteristics and environmental stability.
