Disclosed is a method of manufacturing a multiple-phase particle comprising preparing a channel whose outlet port is adapted to a first fluid, feeding a second fluid into the channel, the second fluid being higher in affinity to the outlet port as compared with the first fluid, feeding a third fluid into the channel, the third fluid being lower in affinity to the outlet port as compared with the second fluid, and introducing the third fluid into the second fluid in the channel while retaining the second fluid at the outlet port by an effect of the affinity of the second fluid, thereby entrapping the third fluid in the second fluid to form the multiple-phase particle.

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.
