Some revolutionary and great storage technology really deserve our attention here. The holographic storage system has become a reality now. This technology has caused a 40-year of hard work in research by the Scientists, which just managed to get commercialized now. InPhase Technologies, which spun off from Bell Labs in year 2000, is planning to ship evaluation units in summer then followed by volume shipments in fall. This storage technology has great size, which it consists of a drive and a 600GB write-once disc that is equivalent to 64 DVDs. The first holographic products are certainly not meant for mass-market. As a 600GB disc will cost around $180, and the drive costs about $18,000.00. Potential users include banks, libraries, government agencies etc.

1. how fast is the read/write speed?
2. i read about a water-based memory some years back - still in research i suppose.

The data transfer rate is about 160Mbits/sec, meaning the read/write speed is 20MB/sec

HOw is that compared with the top DVD burning speeds now?

DVD writes about 1.32MB per second at 1x speed and a multiple of that figure at each speed increment above 1x, e.g 2x writes about 2.7MB/sec

wow, does that mean the read/write speed is as high as for hard disks?

Basically the current DVD RW for 18x or 20x also can reach 20++MB per sec…

[...] We’ve just learned about the great storage size of Holographic storage technology. It’s good to catch up now that some great work and other approaches by other manufacturers. Sony has recently announced that they’ve done some great work for their holographic technology. The improvements by Sony are, adding layers to their disc to increase storage size and also the improvement on transfer rate. For the storage size, Sony managed to bump it up by improving its single-layer Micro-Reflector recording technique to support a full four-layers. It says that Sony has made use of standard blue-violet semiconductor laser diode to write on the 250 μm-thick photopolymer recording layer, with nothing more than a few optical parts added to change the focal point depth in order to write on multiple layers. But there is still work to be done for the improvement, as having the 4 layers is facing some little problem, which the laser will get weaken significantly as well as its transfer rate, while it’s reached the 4th layer. Well, Sony is pretty confident to overcome this problem. Sony’s approach is aiming one day, they could produce a 500GB disc made up of twenty layers packing 25GB a piece. [...]

[...] There are more players now competing to give us better storage technology and medium. After knowing the aggressiveness of Sony and InPhase in the development holographic storage. Here comes another one, the researchers at Nanyang Technological University in Singapore. These reseachers have found a better way, which their kind of rewritable holographic storage medium can be used for storing data and also for manipulating cells and other tiny particles. This holographic system is unlike others, which uses only a single laser that relies on software to calculate the necessary pattern, which simplifies recording. In such a case, the data can be temporarily erased by simply applying a voltage to it and makes it more flexible to be used in various electronic devices. It’s good to have this kind of competition among manufacturers and researchers, so we’ll get better and cheaper technology. [...]

Thanks for a lovely site, I am very impressed
