Optical sample and method of writing and reading information on the same |
摘要 |
An optical sample includes a mask layer made of a material in which an aperture is produced by a chemical change, which is reversible, upon application of heat or light, and a recording layer provided at a position where an evanescent field produced in the aperture when light is applied to the mask layer can reach. Since the aperture is produced in the mask layer by a chemical change, it can be opened and closed at a high speed and hence a high-speed transfer of information can be achieved.
