Abstract

Near-field scanning optical microscope (NSOM) system with a bent or a straight optical fiber probe has been successfully developed to perform optical recording on the surface of cyanine (C35H35ClN2O4) dye layer or Ge21Te26Sb53 phase change (PC) thin film. Optical writing bits < 40 nm on the cyanine dye layer of a commercial compact disk-recordable (CD-R) were shown by atomic force microscope (AFM) images of our tapping mode NSOM. For an vertical reflection mode NSOM, both optical writing and reading can be achieved on Ge21Te26Sb53 PC thin film, and the diameter of 500 nm recording bits are shown.
