Beschreibung
Zusammenfassung:	A holographic information recording apparatus is disclosed. The holographic information recording apparatus comprises a laser light source, a beam splitter, and a reflective spatial light modulator. The beam splitter provides a reference beam and a carrier beam, where that reference beam is directed without reflection toward a holographic data storage medium. The carrier beam is reflected off the reflective spatial light modulator to form a data beam comprising an image of information. The reference beam interacts with the data beam to form a hologram comprising the image. That hologram is then encoded in a holographic data storage medium.
