Optical recording method, optical recording medium, and optical recording system
An optical recording method suited for recording a very small object or movement of a living organism such as a microorganism, which comprises irradiating an informative object set on or above a recording layer comprising a photosensitive material capable of undergoing a storable and detectable photochemical reaction, preferably a polymer material containing a photoreactive component capable of photoisomerization and having in the repeating unit thereof at least one group selected from a urethane group, a urea group, an amide group, a carboxyl group and a hydroxyl group, and recording a distribution of an optical near field generated from the informative object being irradiated on the photosensitive material as a photoreacting quantity of the photosensitive material.
