INTRODUCTION• Rainbow technology, a breakthrough in digital data storage enables us

to store up to a massive 450 GB on just a piece of paper.

• Rainbow Storage is a group of techniques to store digital data in somecolors, color combinations and some symbols known as rainbow

format, and therefore a rainbow picture will be generated.

• With the help of Rainbow system we would be watching full-length

high-definition videos from a piece of paper.



HOW IS IT POSSIBLE?

Data stored in rainbow format on an ordinary paper.



It uses geometric shapes such as squares and hexagons to represent data patterns, instead of the usual binary method that uses ones and zeros torepresent data.

Files such as text, images, sounds and video clips are encoded in "rainbow

format" as colored circles, triangles, squares and so on, and printed as densegraphics on paper at a density of 2.7GB per square inch.

By printing much higher data encoded capacities can be achieved. Theretrieval of data is done by scanning the paper or the plastic sheet containingthe data into a scanner and later reading it over monitor .



Instead of using 0s and 1s, we use color dots where each color dot canrepresent minimum 8 bits (1 byte). The rainbow picture will be highlycompressed and can be represented in any color medium.

"Although environmental light differences and color shading is a problem, it can overcome up to a certain limit by using efficient

mapping functions".



Process of Storing data

• Printing at 1,200 dots per inch (DPI) leads to a theoretical maximum

of 1,440,000 colored dots per square inch.

• If a scanner can reliably distinguish between 256 unique colors, the

maximum possible storage is approximately 140 megabytes for a

sheet of A4 paper.

• If the scanner were able to accurately distinguish between 16,777,216

colors (24 bits, or 3 bytes per dot), the capacity would triple claims of several hundred gigabytes.



At least one of three things must be true for the claim to be valid:

The paper must be printed and scanned at a much higher resolution

than 1,200 DPI,

The printer and scanner must be able to accurately produce and

distinguish between an extraordinary number of distinct color values

The compression scheme must be a revolutionary lossless

compression algorithm.

a lossless compression algorithm that could store 250 GB

within a few hundred megabytes of data. Likewise, data can be

compressed with any algorithm and subsequently printed to

paper as colored dots.



IMPLEMENTATION REQUIREMENTS:

Discs can now be developed from plastic paper

too which will be able to hold 450 GB of data.



The piece of paper or even plastic sheet storing the data has just to be

scanned in the scanner and read over the monitor.

The developer is simultaneously moulding the technology into 'Rainbow

Cards' which will be of SIM card size and store 5 GB of data equivalent to

three films of DVD quality.

As 'Rainbow Cards' will become Popular, Rainbow Card Readers will

replace CD drives of mobile phone and computer notebooks

Large scale manufacture of the Rainbow card will bring down its cost to just

50 paise.



• Principle I

“Every color or color combinations can be converted in to some

values and from the values the colors or color combinations can be

regenerated”.

• Principle II

“Every different color or color combinations will produce

different values”.



COMPARISON WITH OTHER

STORAGE DEVICES

CD, DVD’s a thing of past.



Currently, of the several options available for data storage, DVDs are the best mode, but are yet expensive.

While a CD costs Rs. 15, his paper or plastic-made RVD will cost just aboutRs. 1.50 and will even have 131 times more storage capacity.

Using this technology an A4 sheet of paper could store 450 GB of data. Incomparison, a DVD can store 4.7GB of data.

Paper is, of course, bio-degradable, unlike CDs or DVDs. And sheets of paper also cost a fraction of the cost of a CD or DVD.



ADVANTAGES

The extremely low-cost technology will drastically reduce the cost of storage and provide for high speed storage too.

Files in any format like movie files, songs, images, text can be storedusing this technology.

The biodegradable nature of the storage devices would do away withthe e-waste pollution.

The four main storage devices made using this technology are RVD,

Disposable storage, Data Banks, Rainbow cards.



Rainbow cards can be used in mobile devices in place of DVDs & VCDs.

The rainbow cards can solve this problem. Un-authorized copies of the filmscan be controlled to a certain limits using these cards.

Another theme put forward by rainbow technology is the Data Banks. it is

huge server with a high storage capacity.

As per a research project done in US in 2003 to store the available staticdata, the server required will cost $500 crores(23000 crores). But by usingdata banks ,a similar server can be made with Rs.35 lacks.



DISADVANTAGES

• The paper has the tendency to fade away hence the data loss may

occur.

• With the extremely low cost of using this technology we can always

afford to have multiple copies.



CONCLUSION

Once the Rainbow technology is in, soon we would be watching full-length high-definition videos from a piece of paper!

With the popularity of the Rainbow Technology, computer or fashionmagazines in future need not carry CDs in a pack.

It should cost a lot less to produce than the typical polycarbonateDVDs, CDs and now Blu- rays. Huge data banks can be constructedout of Rainbow-based storage medium.
