Abstract
Techniques are described that can be used to store information onto a holographic storage medium. Techniques are described that can be used to access information from a holographic storage medium. Multiple beam sources and multiple detectors can be used to store and/or read information. At least one detector can be available to read information available from a beam reflected from the medium. Multiple read and/or write operations may take place at substantially the same time.
