Rainbow technology still in the works but holds promise

According to a report from the Arab News, a university technology student named Sainul Abideen has invented a method of storing massive amounts of digital data on a plain piece of paper that he claims could store many times the capacity of the best Blu-ray or HD-DVD discs. In fact, Abideen says that his Rainbow technology can enable him to store from 90 to 450GB on a piece of paper. As far as a real life demonstration of a 450GB paper goes, the technology still needs development.

Abideen, who hails from the Kerala, India, claims that that his Rainbow system is better than a binary storage because instead of using ones and zeros to represent data, Abideen uses geometric shapes such as squares and hexagons to represent data patterns. Color is also used in the system to represent other data elements. According to Abideen, all that's required to read the Rainbow prints is a scanner and specialized software.

The reporter at Arab News claims to have seen 450 pages of fully printed foolscap being stored on a 4-square inch piece of Rainbow paper. The reporter also claimed that he was shown a 45-second video clip that was stored using the Rainbow system on a plain piece of paper. Interestingly, 45-seconds of video isn't a lot, and if the Rainbow system can store up to 450GB, then we need to be watching full length high-definition videos from a piece of paper.

One of the major advantages of the Rainbow system is the fact that it should cost a lot less to produce than typical polycarbonate DVD and CD discs. Abideen claims that huge databanks can be constructed out of Rainbow-based storage mediums. Although the main attraction is cheap paper right now, other media can use the Rainbow system too.

As of right now, Abideen's system is still under research at the Muslim Educational Society Engineering College and although no major companies have expressed interest, Abideen is confident of the system's future. According to the report, Aibdeen is hard at work at developing a Rainbow scanner that would be small enough for integration into notebook computers. If developed, a Rainbow printer will likely be next up.

In other high-capacity storage news, DailyTech previously reported that Hitachi-Maxell is in the progress of producing holographic media for shipment this year. Holographic storage is one of the biggest forward-looking storage technologies and holds a great deal of promise -- as well as data.

Could that much data be stored on one page?

10.5 nches x 8.5 inches x 600 dpi x 600 dpi
= 32,130,000 pixels

450 GB x 1,073,741,824 Bytes/GB x 8 bits/Byte
= 3,865,470,566,400 bits

with 24 colors and 4 colors/ symbol:
(24 x 23 x 22 x 21) = 7,650,720 permutations per symbol

7,650,720 x 30 symbols / 36 cell size (pixels)
= 6,828,267,600,000 Encoded bits

(I adjusted the second set of numbers until I got a reasonable redundancy ratio:

1.766477711 Redundancy Ratio

The math looks very good. It even looks like much more than 450 gb could be encoded on a single sheet of paper. The main limitation is how much CPU processing do you want to do to read the data.

Response-As quoted in my post-

personal Super computer - PSC concept-release 1Q07.
The T-600 series is the kind of stuff we would using very soon.Massive computing power & speeds.

Unquote-PSC is fast becoming an option for day to day use.
As for your Maths & the post-GOOD JOB.

what the beep's wrong with you and your math? none of what you wrote makes sense.

I'm not sure but I think
7,650,720 x 30 symbols / 36 cell size (pixels)

would actually be 6,375,600 (assuming you mean 6x6 pixels = cell size for symbol to take up)

Also, it seems unlikely the symbols would be up to/always be 4 colors each. Just guessing from your limited info on this test case, but 450 GB is total bull I would say.
