RAINBOW TECHNOLOGY


Introduction

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 some colors, 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

HOW IS IT POSSIBLE?

Data stored in rainbow format on an ordinary paper.


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, squares and so on, and printed as dense graphics on paper at a density of 2.7GB per square inch.


Rainbow technology

  • Instead of using 0s and 1s, we use color dots where each color dot can represent minimum 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

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.


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.

    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

IMPLEMENTATION REQUIREMENTS:

Discs can now be developed from plastic paper

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


Rainbow technology

  • 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


Rainbow technology

  • 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

COMPARISON WITH OTHER STORAGE DEVICES

CD, DVD’s a thing of past.


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.


Advantages

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 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.


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.

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


Disadvantages

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

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.
