Extractions: InPhase Technologies will be showing off a holographic video recorder next week with a new type of 3D storage that can hold 20 movies on a single disc Las Vegas is no stranger to bright lights, but next week will see an entirely new laser show as breakthrough technology shows off 3D storage for digital video. InPhase Technologies, an offshoot of Bell Labs, will be showing the first commercial holographic video recorder at the National Association of Broadcasters (NAB) Show on 8 April. The device uses the company's Tapestry technology to hold 100GB of data on a single CD-sized write-once disc as a succession of 1.3MB holograms. That's enough for 20 full-length movies, or 30 minutes of uncompressed high-resolution video: the first product is aimed at professional video-editing, effects and archival use, with initial production at the end of 2003 and full manufacturing in 2004. Tapestry works by splitting a laser beam into two, one of which is modulated by a megapixel array of mirrors in a TI Digital Light Processor chip with a frame of a digital video image. Recombining the two beams in a photosensitive medium results in a hologram containing the interference patterns generated; changing the parameters of the reference beam means that another hologram can be recorded in the same place in the medium as the first without mutual interference. This means a single disc can store a much higher density of information, as one location can hold multiple holograms. The hologram is read out onto a solid-state sensor chip by shining another laser with the same characteristics as the original reference beam onto the hologram: this produces the original image.
Extractions: We're in the middle of a wireless revolution, and next year will be more of the same. Bluetooth is working and cheap, 802.11a and 802.11g will bring 55 megabits a second to your radio network, and a whole host of small, cheap, low power devices may yet give us the automated, computerised home that we've promised ourselves since the 1950s. Look out for Zigbee, the low power, low speed technology promised to be cheaper than Bluetooth and to run for months on ordinary batteries, but it has competitors; with Microsoft launching Bluetooth systems that don't work with other Bluetooth devices, beware the fragmentation of the market into different semi-standards. 2. Location-based services You might not know where you are, but your mobile phone does. The network operators are already talking about beaming adverts to your phone or PDA when you're in the vicinity of a shop; somewhat more usefully, the same technology will tell you where to get petrol, cash, food or help, and automatically summon the closest free taxi to you. At the same time, GPS satellite navigation technology is getting much cheaper and more reliable and will be built into more things. Including active pet-collars, although quite why you'll need to know where Tiddles is to within five metres anywhere on the earth's surface is not entirely clear.
Trying To Outpace Quickly Growing Demand Whereas some storage hardware will be developed to Future Watch Expanding capacitystorage technology during holographic memory offers the best hope beyond http://www2.idg.com.au/infoage1.nsf/04c52135f89305774a2568ac00109437/225134960c1
Extractions: We've come a long way since the punch cards of decades past. IBM first commercially introduced data storage in 1967, and since then storage densities have increased more than 1 million times. Nevertheless, the explosion of e-business data is putting the crunch on enterprise storage; capacities are quickly becoming exhausted under the attempt to manage the information glut. Storage vendors are scrambling to extend the lifespan of magnetic disk drives by supplementing them with new technologies. For example, backed by support from companies such as Quantum and Maxell, TeraStor is forging an optical hybrid that could improve enterprise storage capacities sevenfold. Other approaches include looking for smaller magnetic material to coat drive surfaces and pack more bits into the same amount of space. Hard drive manufacturers are also adapting new component technologies to the task in an effort to increase drive speeds. IBM is even working on a variation of punch card storage, using a souped-up polymer and heated stylus to store microscopic indentations on a plastic surface, comparable to a vinyl LP. With lower costs and improved storage capacity, it could prove an alternative to magnetic storage in meeting future storage needs.

Extractions: Xu Xuewu The demand for high-capacity data storage technology is increasing tremendously with the rapid development of computers, the Internet and multimedia entertainment. Holographic data storage can potentially meet this demand as it holds the promise for a digital storage system with terabyte storage capacity, faster transfer rates in the gigabits per second range and short access times of less than 100 microseconds. Current magnetic and optical storage technologies cannot provide all these features simultaneously. Recording Principle Holographic storage is basically an optical imaging technique that stores digital information three-dimensionally. As shown in Fig.1, the key components of a holographic storage system include a laser source, a spatial light modulator (SLM), a charge-coupled device (CCD) detector array, beam deflector optics and a recording medium - usually a photorefractive crystal or a photopolymer.

Extractions: Cruise and his fellow cops obviously haven't heard of networking. Every time they need to play back a video file, they have to dig up a disk from a drawer. The disk itself looks like a palm-sized plate of perspex. The transparency of the media seems to indicate that it's some kind of light-coded storage. Holographic storage, to be exact. Several firms today are chasing the Holy Grail of holographic storage . At the current explosive rate of data creation, contemporary technologies such as hard disk storage and DVD writables will prove inadequate in a few years. Holographic storage, with its promise of packing incredibly dense amounts of data per unit volume of media, is one candidate as the universal storage format of the year 2054. Take a computer screen filter and pretend it's one of the cool transparent monitors that everyone uses in 2054. Take a compact disc case and separate the lid from the body. Glue the body to the monitor screen: It's your "media slot". The media? The cool transparent compact disc lid you're holding in your hand, of course.

Extractions: Short for third generation and usually used to describe the most recent wave of mobile communications. While analog technology represents the first generation of mobile communication technology and digital represents the second, third generation technology will provide more bandwidth for mobile devices. Speeds of 384Kbps (kilobits per second) will be possible while on foot and 144Kbps while traveling in a car. This kind of speed allows for a host of multimedia applications within a 3G network. all-in-one graphics boards Graphics boards that have MPEG (Moving Picture Experts Group) players and video capturing editing features. Whereas older boards supported 3-D graphics, all-in-one boards can also handle DVD (digital versatile disc) technology, high-resolution capturing, and even TV tuners. Bluetooth A technical industry standard that allows wireless connections between portable devices and among portable devices and home and business devices. With a special transceiver chip, PDAs (personal digital assistants), notebook PC, and cell phones can connect with another device, such as a PC, in a short range (the same room) or a longer range (throughout a house).

[Contents] 3.4 Technology trends Table 3-2 presents the current and the 2005 projected characteristics for memory and processors, taken from Estimated evolution of performance and cost for memories, processors, and disks. Memory 0.35 mm feature size 64 Mbits/chip 30 CHF/Mbyte 0.13 mm feature size 4000 Mbits/chip 0.50 CHF/Mbyte High-end processors 25 kCHF/system 5 kCHF/system Low-end processors 6 kCHF/system 1 kCHF/system Magnetic disk 400 CHF/Gbyte 6 Mbyte/s-disk 12 CHF/Gbyte multi-Gbyte/s per system Memory is expected to quadruple in capacity every three years due to decreasing feature size and increasing chip size. The fabrication facilities are currently financed and/or built for a feature size of 0.18 m m, and thus, new technology will be needed to reach the 2005 numbers. Memory capacity is not a major issue for LHC event processing farms - default system memory will be sufficient for event-by-event processing. However, the dropping cost will certainly influence the interactive analysis facilities where 10-100 Gbyte memory will be affordable. Here one can begin to imagine systems where frequently accessed data are maintained in memory, allowing to effectively utilize memory access speeds which are over 1000 times faster that disk access. From Table 3-2 one sees an estimated increase of 10 in unit computing power and a factor of 50 in computing power per unit cost. Note that this estimate includes a speculative increase of a factor of three from the number of instructions executed during each chip cycle. It is not clear today whether this type of parallelism will be pursued by the manufacturers. From these estimates, the very large aggregate processing capacity required for ATLAS appears to be affordable, but this will require an enormous number of processors. Thus, how these processors are interfaced, or the system architecture, becomes an important issue. One potential architecture is Scalable Parallel Processors where physically independent computers are interconnected by a high performance switch with a special interface which enables it to be used with a low hardware and software overhead (as opposed to a standard network connection).

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: The design combines current research into optical holographic data storage with data-encoding algorithms evolving from our research on software data compression, to increase data-storing capacity. There is no theoretcal limit to the redundant use of physical storage media by the this design; however published research on optical holography for data storage suggests a capacity increase on the order of hundreds to thousands over existing technology. HIERARCHICALLY MULTIPLEXED OPTICAL RECORDING SYSTEM FOR STORAGE OF DIGITAL DATA Summary of Principle U.S. Patent Nos. 4,958,338, 5,038,335 PRIOR ART: To date, digital data storage has relied almost exclusively on binary numeric representation. Though simple and efficient, this method represents the least effective use of each unit of physical storage, since a binary digit is the absolute minimum quantity of information. Technical advances which have increased storage capacity have been limited to discovering means to pack more binary units into a given amount of storage media, a strictly linear increase. Recently, interest has been growing in digital storage based upon optical holograms. These systems commonly use a two-dimensional matrix of binary cells (a "page") as the base image. These pages are then multiplexed by varying one of the recording signals along a dimensionalized property like wavelength or angle of incidence.
