INTRODUCTION

Rainbow technology a breakthrough enable us to store up to 450 GB on just a piece of paper.

Rainbow Technology is a developed by paper-based data storage technique .

Rainbow Storage is a group of techniques to store digital data in colors, color combinations and symbols.

known as rainbow format and a rainbow picture will be generated.

o With the help of Rainbow system we can watch full-length high-definition videos.

HOW IS IT POSSIBLE?

Data stored in rainbow format on an ordinary paper.5

Page 6: Rainbow technology

It uses geometric shapes such as squares and hexagons to represent data patterns.

Instead of the usual binary method that uses ones and zeros to represent data.

Files such as text, images, sounds and video clips are encoded in "rainbow format" as colored circles, triangles and so on.

And printed as dense graphics on paper at a density of 2.7GB per square inch.

By printing much higher data encoded capacities can be achieved.

HOW IS IT POSSIBLE? (cont)

Page 7: Rainbow technology

The retrieval of data by scanning the paper or the plastic sheet containing the data into a scanner and reading it over monitor .

Instead of using 0s and 1s, we use color dots where each color dot can represent 8 bits (1 byte).

The rainbow picture will be highly compressed 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 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 MB 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 100 GB.

Page 9: Rainbow technology

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.

Process of Storing data (cont)

Level 1-Data to Data Picture:

Data to Data Picture conversion takes place in four steps.

• A chunk of data bits are taken from data source , which is known as a word.

• The word can be converted into a value that will be unique for each different combination of bits.

• The value then passes through error checking mechanisms. After producing error correction bits, it will attach to the data picture.

• Thus the final output (Data Picture) will be generated.

Level-2 Data Picture to Data:

Data Picture to data conversion uses just the reverse process. • Data Picture is taken as an input.

• Value mapping functions are used for mapping the arrangements done on actual data.

• Some errors that occur due to colour fading can also be handled at this stage. The values are passed through error correction machine.

• Then the value to word conversion takes place. The encoded Data Picture is hence decoded into the result data which will be the original data.

IMPLEMENTATION REQUIREMENTS

Discs can now be developed from plastic paper too which will be able to hold 450 GB of data.

13

Page 14: Rainbow technology

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.

14

Page 15: Rainbow technology

This technology is based on two principles:

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.

16

Page 17: Rainbow technology

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 about Rs. 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. In comparison, 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.

17

Page 18: Rainbow technology

ADVANTAGES

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

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

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

The four main storage devices made using this technology are RVD, Disposable storage, Data Banks, Rainbow cards.

18

Page 19: Rainbow technology

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 films can 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.

Larger amount of data can be had on lesser space.

19

Page 20: Rainbow technology

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 fashion magazines in future need not carry CDs in a pack.

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