摘要
The present invention relates to a method for optical recording in which information is recorded on an optical recording media utilizing holography and to a method for optical reproducing in which information recorded on an optical recording media utilizing holography is reconstructed. The methods includes preparing an optical recording media having wavelength reference marks with a periodic structure which are associated with a recording base wavelength, irradiating the wavelength reference marks with a beam from a light source on recording information or on reproducing information to detect a wavelength shift of the light source with respect to the base wavelength based on a diffraction beam from the wavelength reference marks, and performing recording or reproducing while controlling the wavelength of the light source so as to reduce the wavelength shift.
