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 (C₃₅H₃₅CIN₂-O₄) 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 were shown by atomic force microscope 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.
