Abideen claims to have placed a 45 second video clip on a single sheet of paper, with the possibility of up to 450GB on the horizon - Image courtesy Arab News
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.

OK maybe havend done my home work BUT

A A4 paper is a bout give ore take 100 square inch.
I will presume some tings

you use a 1200 DPI laser printer
you use a 2400 DPI scanner (higher res. to compensate for reading errors)

for easy calculation we make the paper square 10" x 10"

lets say you take for every dot 256 colors so every dot is a byte

then you get +/-
((((1.200x10=12.000)X(1.200x10=12.000)=144.000.00 0)/1024=140.625KB)/1024=137MB)

You properly can get te color resolution up a factor of 10 so you would get over 1GB uncompressed data on 1 A4,
Before te cost of equipment gets really expensive

So i don't see how you can get up to 450GB, unless i missed something in the article i don't see how you can get 450 times that extra, whit some smart algorithm.

Still its interesting technique and could be really use full for tech/computer magazine's to have a block on the end of a article whit the background info.

So i am really wondering how they got up to 450GB.
Ore the reporter wroth down what would be the theoretical max, end say that it would get mouths when they start building

This logic has one flaw - mechanically, you can't print on the edge of the paper where you hold the most data. Also, printers don't print single shades of colors, they print in single color dots that "look" like a shade of colors if they are gapped on white paper. This means that you have to calculate the color for a larger region of paper, lowering your data density. Perhaps paper or laser printing will never be the solution to data storage.
