One Terabyte On a 12-inch^H^H^H^Hcm Disk
News for nerds writes: "At InterOpto'02 - international optoelectronics exhibition hold in Chiba, Japan - OPTWARE Co.Ltd. made up of ex-Sony engineers, demoed(in Japanese) 1-terabyte super-high speed optical disk system "T-VRD." It uses hologram and stores 1 terabyte data in a 12-cm-CD-size disc, with 100Mbps - 1Gbps transfer rate. Available in 2003 as 19-inch rackmount, 2005 for PC." Update: 07/16 18:33 GMT by T : Sorry, that's centimeters, not inches, which is of course even better ;)
There's a big difference there....
- Despite popular opinion, I am not perfect.
And of course, it's 120 mm = 12cm != 12 inches ~= 36 cm...
Because CD-media size is a must !Basically, they:

Let's do you video calculation again. If memory serves compressed HDTV is about 19MB/second. Let's call it 20MB/second to make the calculations easier. So 1 terabyte gives us about 50,000 seconds. This is about 13-14 hours. So we are looking at about 13 hours of HDTV.
The corporation optical wear the 1TB (the tera- byte) announced the optical disk technology " tera- byte optical disk system " whose it is possible to write capacity, to the disk of 12cm CD size in the comprehensive exhibition " InterOpto'02 " of optical industrial technology.

From the past it is researched, applying the " hologram system ", the system which was developed. With hologram system of conventional type there was a problem in compatibility and the like of the existing media such as miniaturization and cost and DVD. With the technology which this time is announced, you say these weak points were overcome by using the same company individual " polarized light Cori near hologram technology " and so on.
Hologram technology until recently, using two object glasses, had the necessity to irradiate separate " reference beam " and " signal light ". You say with polarized light Cori near hologram technology these from one object glass the economical space, cost decrease is actualized by the fact that it makes lighting possible. In addition, we have assumed it can maintain also the compatibility of the DVD and the CD media.
Difference of data record method such as CD drive Device of record to tera- byte disk
Those where the reflecting horizon where structure of the tera- byte disk media puts the cubic measure hologram record material with the disk baseplate of the glass make, the pre- format is done is pasted in the one side. It is not the glass in the future, you call the schedule where the disk baseplate of the plastic make is used. In addition, at the beginning the media of the is offered, but you say relying tub Lu it will be able to offer also the media in the future.
At the time of data record, signal light and reference beam are irradiated vis-a-vis this reflecting horizon, reference beam and the information light which are reflected to interfere inside the cubic measure hologram material, the data is recorded to the interference fringes which occur.
When grasping the device which grasps the hologram which irradiates only reference beam, is recorded to the cubic measure record material.
With the former DVD and CD drive, using single laser light, it does reading and writing, but with hologram technology, the bundle of the light whose large number is thin is used. In addition, the data was recorded until recently level at the bit unit, but with hologram record, it is possible to record to three-dimensional cubic measure hologram layer as a page data.
Because of that, with the disk media which uses hologram, it is possible to write the data of 3 ten thousand bit inside hologram of diameter 500 mu m. While the respective hologram to be piled up, because it is existence possible, we have assumed it is suitable for large increasing capacity. In addition, only the 1bit data transfer could do with the pickup of former DVD/CD drive, at one time, but because with hologram system the data of 3 ten thousand bit can be read and written at one time, also data rate improves substantially, you say data transfer with the 100Mbps - the 1gbps becomes possible.
Appraisal device " T-VRD " of the tera- byte optical disk system was displayed in the InterOpt meeting place, demonstration was done. At the same company, at the beginning we have assumed, introduction in TV station and the Government agency is anticipated, we have assumed on end of 2003 offer of 19 inch rack-mounted type system, furthermore it miniaturizes drive itself in 2005, it develops in for the foam/home server and the PC market as a consumer product.
The drive part of T-VRD When drive was opened. As for the media being stored by the cartridge, it is The corresponding disk was displayed from each company
Actually hologram it was recorded the media As for this way unused media. The record aspect has like the mirror high reflectance
Yoshio Chairman and CEO Aoki Chief Executive Officer
At the announcement meeting place, Yoshio the Aoki of Chairman and the CEO Chief Executive Officer greets, " presently in communication industry, per second also the 1TB thing data has become transmission possible. This the movie of 2 hours is something which is made transfeable in 0.1 seconds. Is, but when it reaches the point where it can exchange the large capacity data instantaneously, even on the storage side which retains that data large capacity and high speed the media which had transfer speed becomes necessary ", necessity of the tera- byte optical disk system was expressed.
" With the former CD and DVD drive, NA value of the object glass was increased, precision of recording density was increased by the fact that wave length of the laser is reduced. Is, but with this method already the limit has been visible ", also you talked, the disk system which uses hologram emphasized that it is the system which system differs until recently completely.

As for the 100GHz machines, unless clustering has induced much more delay than I am used to expecting, you would still need many of those to render realistic virtual worlds on the fly, given the time it took to render scenes on render farms for films like Monsters, INC., toy story, FF:TSW, and others. a 10THz machine, with well optimized code, however, should be able to pull it off. Your 100GHz machine though would almost certainly be able to throw a primitive polygon-based version in realtime. Anyway, just my $0.02.
