“…Although the research of HDS was began in the 1960s and followed through 1970s [5][6][7][8][9], but no commercial products came out of these efforts because of the significant technical challenges, including poor media performance and a lack of input and output devices such as spatial light modulators (SLMs) and cameras. In the mid 1990s, the Defense Advanced Research Program Agency (DARPA) of United States formed a consortium of companies and universities, led by IBM and Stanford University, to develop high performance holographic storage systems [10,11].…”

Nowadays, big-data centers still rely on hard drives. However, there is strong evidence that these surface-storage technologies are approaching fundamental limits that may be difficult to overcome, as ever-smaller bits become less thermally stable and harder to access. An intriguing approach for next generation data-storage is to use light to store information throughout the threedimensional (3D) volume of a material. Holographic data storage (HDS) is poised to change the way we write and retrieve data forever. After many years of developing appropriate recording media and optical read-write architectures, this promising technology is now moving industriously to the market. In this paper, a review of the major achievements of HDS in the past ten years is presented and the key technique details are discussed. The author concludes that HDS technology is an attractive candidate for big data centers in the future. On the other hand, there are many challenges ahead for HDS technology to overcome in the years to come.

“…Broadly, this category includes other polymers (RNA, protein, lipid, carbohydrate;Mercer et al, 2008;Routtenberg, 2008) or submolecular forms perhaps related to 'quantum computing' (Venema, 2008). Also in this category is the idea of the brain as a three dimensional holographic storage network (Heerden, 1963;Pribram, 1971).…”

“…1 The potential for a dramatic increase in the storage capacity offered by volume holograms was considered early by Van Heerden. 1 The success of any new technology depends critically on having suitable materials. A desirable holographic material is one that can accurately record an optical interference pattern, preferably as a volume phase hologram.…”

We describe the storage of 2000 images of resolution 512 ϫ512 pixels as a regular matrix pattern of 10ϫ10 elements, where each element is angularly multiplexed 20 times in a 25-m thickness of dichromated gelatin emulsion without crosstalk effect. The surface area of the matrix is 1 cm 2 . We show good concordance of the angular selectivity between the experimental result and theory. The diffraction efficiency of each of the 20 multiplexed images has been measured and has nearly the same value. Examples of reconstructed images for multiple applications are given, for example, storage of 160,000 images on a 3 1 2 -in. floppy-disk format, that is, about 100 minutes of black-and-white films. Applications to automobile cartography and for storing x-ray and weather forecast images are possible. Colored diffractive images are also possible and are illustrated.
