More Information
Summary:A recording apparatus performing at least recording with respect to a hologram recording medium is disclosed. The recording medium includes: a light emitting means for emitting light to be radiated with respect to the hologram recording medium set at a prescribed position; a spacial light modulation means configured to be able to generate reference light and signal light to be radiated to the hologram recording medium by performing light intensity modulation to incident light in the unit of pixels; a phase modulation means for performing phase modulation to radiated light from the special light modulation means; and an optical system configured to guide light emitted from the light emitting means with respect to the hologram recording medium through the spacial modulation means and the phase modulation means.
