Near-field interactions appeared between recording marks beyond the diffraction limit

It is shown that the mark pattern and size become very important factors, not only when the observation is done beyond the diffraction limit, but also when amplifying super-RENS effect. The results are also important because one-dimensional photonic crystal in a very local area can easily be fabricated and obtained by optical recording at very high speeds without electron beam nor lithographic technique. Closing or growing a light scattering center like Ag clusters in the AgO/sub x/ layer, the super-RENS system will work as photonic devices, such as optical switches and transistors.
