Abstract:
In a system (apparatus and method) which employs a light absorbent material surrounded by an optically transparent matrix as a recording medium and in which the presence or absence of emission light of a specific wavelength from unity of the light absorbent material is used for optical writing and reading, the light emitted in response to reading light is condensed and spectrally diffracted and the light intensity is detected for each specific wavelength and related to recorded information.
