Abstract
The present invention provides a solution to the needs described above through a system and method for holographic storage. The system comprises a laser light source, a first beam splitter for splitting a light beam into an object and reference beam, an elliptical reflector with a first and second focal point, a reflector rotatable about a first axis and a second axis, a pattern encoder, and a holographic storage medium. The reflector is located at the first focal point of the elliptical mirror, and the holographic storage medium is located at the second focal point of the elliptical mirror.
