Rainbow technology, a breakthrough in digital data storage allows us to store up to a vast 450GB on simply a chunk of paper. Rainbow Storage could be a cluster of techniques to store digital knowledge in some colours, color mixtures and a few symbols called rainbow format, and so a rainbow image are going to be generated. The technique is employed to realize high-density storage. With the assistance of Rainbow system we might be observance full-length high-definition videos from a chunk of paper!
The main attraction is that the low-cost paper. The Rainbow technology is possible as a result of written text, legible by the human eye could be a terribly wasteful use of the potential capability of paper to store knowledge. By printing the info encoded in a very denser method a lot of higher capacities is achieved. Paper is, of course, bio-degradable, not like CDs or DVDs. And sheets of paper additionally value a fraction of the price of a CD or optical disc.
This boon to digital knowledge storage is developed by Sainul Abideen, university technology student at the Muslim academic society Engineering school in Kerala.
HOW IS IT POSSIBLE?
Data keep in rainbow format on a normal paper.
It uses geometric shapes like squares and hexagons to represent information patterns, rather than the same old binary methodology that uses ones and zeros to represent information. Besides, color is additionally employed in the Rainbow system, to represent different information parts. Files like text, images, sounds and video clips ar encoded in "rainbow format" as coloured circles, triangles, squares then on, and written as dense graphics on paper at a density of two.7GB per area unit. associate degree RVD thus sounds like a print-out of the trendy art.
The paper will then be scan through a specially developed scanner and therefore the contents decoded into their original digital format and viewed or compete. The Rainbow technology is possible as a result of written text, legible by the human eye may be a terribly wasteful use of the potential capability of paper to store information. By printing the information encoded during a denser method abundant higher capacities will be achieved. The retrieval of knowledge is finished by scanning the paper or the plastic sheet containing the information into a scanner and later reading it over monitor. rather than victimization 0s and 1s, we have a tendency to use color dots wherever every color dot will represent minimum eight bits (1 byte). The rainbow image are going to be extremely compressed and might be portrayed in any color medium. For retrieving the contents from the medium, image will be captured and information will be generated from the colour combos. "Although environmental light-weight variations and color shading may be a drawback, it will overcome up to an exact limit by victimization economical mapping functions".
IMPLEMENTATION REQUIREMENTS:
Discs will currently be developed from plastic paper too ready to} be able to hold 450 GB of information.
In order to scan the Rainbow prints, all that's needed may be a scanner and specialised software package. Smaller scanners might work within portable computer computers or mobile phones, and skim SIM card-sized RVD's containing 5GB of information.
The recording media can be either paper or plastic sheets. The piece of paper or maybe plastic sheet storing the info has simply to be scanned within the scanner and skim over the monitor. A scanning drive supported the Rainbow software package has at the same time been developed which can are available in smaller sizes to be at first carried with the laptops and later to suit into their bodies.
The developer is at the same time moulding the technology into 'Rainbow Cards' which can be of SIM card size and store five GB of information admire 3 films of optical disc quality.
As 'Rainbow Cards' can become fashionable, Rainbow Card Readers can replace CD drives of mobile and laptop notebooks and can change additional knowledge in transportable forms for mini digital readers. giant scale manufacture of the Rainbow card can bring down its value to only fifty paise
DEMONSTRATION:
Sainul Abideen ,the developer explains the feature of his inspiration - rainbow technology
The newsman of Arab News claims to possess seen 450 pages of totally written sheet being keep on a 4-square in. piece of Rainbow paper. The newsman conjointly claimed that he was shown a 45-second video clip that was keep exploitation the Rainbow system on a visible piece of paper. Abideen has incontestable a 45-second video clip being encoded on paper, termed by him, a rainbow video disk - RVD - so compete back through a laptop with Associate in Nursing RVD scanner connected. In another demonstration that he has shown 432 A4 pages of paper rainbow format-encoded and keep on a two-inch by two-inch sq. of paper.
COMPARISON WITH alternative STORAGE DEVICES:
CD, DVD’s a factor of past.
Currently, of the many choices offered for knowledge storage, DVDs area unit the simplest mode, however area unit nonetheless pricey. Sianul has same that a CD or optical disc consumes 16gms of polycarbonate, that may be a crude by-product.
whereas a CD prices Rs. 15, his paper or plastic-made RVD can value almost about Rs. 1.50 and can even have 131 times additional storage capability.
Using this technology Associate in Nursing A4 sheet of paper might store 256GB of information. compared, a optical disc will store four.7GB of information.
Paper is, of course, bio-degradable, not like CDs or DVDs. And sheets of paper conjointly value a fraction of the price of a CD or optical disc.
ADVANTAGES:
• Data are often keep on a standard paper.
• Abideen claims that vast knowledge banks are often created out of Rainbow-based medium.
• Larger quantity of information are often had on lesser area.
• The very low-priced technology can drastically cut back the price of storage and supply for top speed storage too.
• Files in any format like motion picture files, songs, images, text are often keep exploitation this technology.
• The perishable nature of storage devices can do away with e-waste pollution.
• The four main storage devices created exploitation this technology area unit RVD, Disposable storage, knowledge Banks, Rainbow cards, and answer to the storage issues sweet-faced by the pc world.
• With the assistance of disposable storage,a high density knowledge storage is formed doable even on paper or plastic sheets,any style of laptop files are often keep and distributed this manner,so rather than giving cd’s with the pc magazines,its content are often written in a very page,video albums, software package etc.Can be distributed at avery low value with the assistance disposable storage
• Rainbow cards are often employed in mobile devices in place of DVDs &VCDs.In a area unit sized rainbow cards, (equivalent to the dimensions of sim card)more than 5GB knowledge are often keep.A major crisis sweet-faced within the style of the tiny digital devices is that the immense size of the CD/DVD drives.The rainbow cards will solve this downside.Un-authorized copies of the films are often controlled to an exact limits exploitation these cards.A UK-based company has already evinced interest in creating rainbow cards
• Another theme advocate by rainbow technology is that the knowledge Banks;it is large server with a high storage capability.As per a groundwork project tired United States of America in 2003 to store the avaible static data(films,songs,tutorials displays etc)the server needed can value $500 crores(23000 crores).But by exploitation knowledge banks ,a similar server are often created with Rs.35 lacks.All;the offered films and alternative static knowledge are often employed by paying money with the net.Almost 125.603 atomic number 82 knowledge storage is feasible in a very knowledge Bank.
• Sainul is busy with project Xpre3ssa currently.It’s a software package package for regional languages. By exploiting news papers, stories and novels etc….. are often created audible in it’s own vogue.so on-line news papers and novels are often enjoyed through mobile with a GPRS affiliation.Sainul Abideen, a native of Karingappara , is a
freelence software package developer.
• Un-authorized copies of the films are often controlled to an exact limit exploitation these cards.
DISADVANTAGES:
The paper has the tendency to turn thus the info loss could occur.
With the very low value of exploitation this technology we are able to invariably afford to possess multiple copies.
CONCLUSION:
Once the Rainbow technology is in, before long we might be looking full-length high-definition videos from a chunk of paper! With the recognition of the Rainbow Technology, laptop or fashion magazines in future needn't carry CDs in a very pack.
one in every of the foremost blessings of the Rainbow system is that the undeniable fact that it ought to value plenty less to supply than the everyday polycarbonate DVDs, CDs and currently Blu- rays. immense knowledge banks are often created out of Rainbow-based medium.
