PROBLEM TO BE SOLVED: To obtain a method for storing and reading information stably and with high density in and from a carbon nanotube. SOLUTION: Information is stored in the carbon nanotube by performing a step for preparing a surface modified carbon nanotube material (4), a step for immersing the surface modified carbon nanotube material (4) in a solvent (2) containing a dopant generating intercalation and a step for storing information by applying an electric field to a desired point of the surface modified carbon nanotube material immersed in the solvent to change optical characteristics of the desired point. When information is read out, Raman spectrometry of the carbon nanotube material is utilized. COPYRIGHT: (C)2006,JPO&NCIPI
