Jefferson , B. Marcus , R. M. Macfarlane , R. M. Shelby , and G. T. Sincerbox We present an overview of our research effort on volume holographic digital data storage. Innovations, developments, and new insights gained in the design and operation of working storage platforms, novel optical components and techniques, data coding and signal processing algorithms, systems tradeoffs, materials testing and tradeoffs, and photon-gated storage materials are summarized. With its omnipresent computers, all connected via the Internet, the Information Age has led to an explosion of information available to users. The decreasing cost of storing data, and the increasing storage capacities of the same small device footprint, have been key enablers of this revolution. While current storage needs are being met, storage technologies must continue to improve in order to keep pace with the rapidly increasing demand. However, both magnetic and conventional optical data storage technologies, where individual bits are stored as distinct magnetic or optical changes on the

Extractions: By Gregory T. Huang September 2005 Page 1 of next Although the offices of IBM and Hewlett-Packard are nearby, Longmont, CO, is decidedly not Silicon Valley chic. But in this Denver suburb, a radical experiment in data storage is under way. At the headquarters of InPhase Technologies, where the conference rooms are named after ski resorts, chief executive Nelson Diaz holds up a clear plastic disc, about the size of a DVD but thicker, and pops it into a disc drive. A laptop connected to the drive downloads streaming video of an old episode of Seinfeld as the drive writes it to the disc. But this is no ordinary recording process. The disc has more than 60 times the storage capacity of a standard DVD, while the drive writes about 10 times faster than a conventional DVD burner. That means the disc can store up to 128 hours of video contentalmost twice enough for the full nine seasons of Seinfeldand records it all in less than three hours. It's likely to be one of the first commercial systems to use "holographic storage," in which bits are encoded in a light-sensitive material as the three-dimensional interference pattern of lasers. Unlike CDs and DVDs, which store data bit by bit on their surfaces, holographic discs store data a page at a time in three dimensions, enabling huge leaps in capacity and access speed. And InPhase, a 70-person startup spun out of Lucent Technologies' Bell Labs in Murray Hill, NJ, is leading a handful of companies racing to commercialize this optical storage breakthrough.

Extractions: Data storage on optical discs has been of critical importance to electronic musicians and consumers ever since CDs first appeared two decades ago. Since then, the capacity of those 12 cm plastic discs has increased from 650 MB to 4.7 GB on DVD to 25 GB on blue-laser discs, which will hit the U.S. market within a year or two. While 25 GB sounds like a lot, experience teaches us that we will soon outgrow even that capacity, and the basic idea of representing bits of information as pits and lands in a spiral track on the disc probably can't be extended much further. However, there is hope for creating optical discs with much greater capacities, thanks to a different approach: holographic encoding. What seemed like a sci-fi dream just a few years ago will soon be an actual commercial product, thanks in large part to a company called InPhase Technologies ( www.inphase-tech.com

Perhaps you have a bank credit card containing a logo in the form of a hologram . The idea is to use this type of technology to store computer information. The goal is to store a lot of data in a little bit of space. In the foreseeable future, the technology is expected to yield storage capacities up to a terabyte in drives the same physical size as current ones. A terabyte would be enough space for hundreds of movies or a million books. Although no one has yet mass-commercialized this technology, many vendors are working on it. InPhase Technologies, which was founded by Lucent, is working on a product capable of storing 200 gigabytes of data, written four times faster than the speed of current DVD drives. Although current versions are not rewritable, the company expects to make holographic storage that can be rewritten within the next few years. The first products are likely to be expensive, and only feasible for large organizations with unusual needs for storage. However, vendors expect to make holographic storage available and affordable for the average consumer within the next few years.

Holographic Data Storage Optimisation of a novel photopolymer for use in holographic data storage increased automation of data storage hardware/software, use of peristrophic http://www.ieo.dit.ie/holographicdatastorage.html
Extractions: Optimisation of a novel photopolymer for use in holographic data storage Main Contact: Hosam Sherif In 2002, it was estimated that people produced 5 exabytes (5 billion gigabytes) of data [1], the majority of which was in digital form. Since this figure is always growing and analogue media is constantly being converted to digital, new methods of storing this data are needed. Currently the two main storage methods i.e. magnetic and optical are just about keeping ahead of these needs; unfortunately this is not always going to be the case. The limit of hard drive storage is expected to be reached within the next ten to fifteen years [2]. By then magnetic bit sizes will be so small that phenomenon such as the super paramagnetic effect (SPE) and shot noise will cause the polarity of the magnetic fields to flip randomly. Likewise, optical disks such as DVDs may reach their maximum capacity due to the diffraction limit of the laser light used. The aim of this work is to test and optimise novel photopolymers developed in the IEO for use as holographic data storage medium. To facilitate this, an integrated optical set up has been constructed. The system is capable of functioning in two distinct ways. Firstly, it can be used as a method of characterising a photopolymer in terms of M/#, temporal stability, and angular selectivity. Secondly, with the insertion of a spatial light modulator the system along with relevant optics (collimator, polariser, CCD camera), can be used to record and read back page wise data.

Holographic Storage Nears Debut During that time, hardware advances carried out independent of holography have As enthusiastic as the researchers are about holographic storage media, http://colossalstorage.net/eetimes.htm
Extractions: (04/26/01, 10:59 a.m. EST) or more than 20 years researchers worldwide have pursued the Holy Grail of holographic data storage, an optical method of storing massive amounts of data in small areas by writing data as light patterns in three dimensions on a filmlike medium. During that time, hardware advances carried out independent of holography have made holographic storage more achievable. These include such improvements as CMOS sensor technology, development of spatial light modulators using ferroelectric liquid crystals and mirror arrays, and reduction in the cost and size of shorter wavelength green lasers. Yet the biggest challenge has been to find the right material for the recording medium, one that works and is inexpensive enough to produce commercially. In the last year, some research groups at universities, corporations, government labs and startups claimed to have found the material that will propel the technology forward and enable its adoption in commercial storage media products in two to three years.

Extractions: Holographic Storage from Hitachi In 2006? By Brian Carnell Sunday, January 23, 2005 InfoWeek reports that Hitachi plans to begin sampling a 5", 200gb holographic disk in 2005 and incorporate the technology into drive system in 2006. According to Infoweek, Hitachi hopes to increase capacity to 400gb in 2007. Tom's Hardware has more technical details about InPhase, the holographic disk company that Hitachi acquired and which will actually be producing holographic drives for the company. According to Tom's Hardware, The prototype drive records data into InPhase's patented two-chemistry photopolymer WORM material. The recording material is 1.5 mm thick and is sandwiched between two 130 mm diameter transmissive plastic disk substrates, the company said. The prototype can arrange more than one million bits of data into a single page, which is recorded with a single flash of a 407 nm laser beam, according to InPhase. Multiple pages of data, referred to as a book, are recorded in one spot on the disk providing approximately 12 MByte of data in a single book location. The holographic disk will apparently be available eventually in sizes up to 1.6 TB.
