- Abstract
- A holographic data storage prototype fully integrated with electronics for video demonstration has been developed. It can record data in several tracks of a photopolymer disk and access them arbitrarily during retrieving process from the continuously rotating disk. An embedded controller operates all of the optomechanical components of the prototype automatically and electronic parts conduct adaptive data readout of channel data up to 55 megabit per sec. For real-time video demonstration, video stream are recorded in four concentric circular tracks of the disk. Each recording spot contains about one hundred pages with angle multiplexing. The eleven minute length video data are successfully reconstructed from the prototype.
