the small size and high capacity
storage devices. But instead of
inventing a new storage device for our
future needs, there is a new
technique to store enormous amount
of data in nowhere else, but in a paper.
You can store an awesome amount of data about 250GB of data in just a sheet of A4 paper. This new technology is the ‘Rainbow ‘. Rainbow technology is the upcoming storage technology and it is currently in its developmental stage. So, how it is
done? Read below to find it out more..
Rainbow Versatile Disk
What’s behind it?
This technology uses geometric
shapes to store data instead of the
usual digital format of 0′s and 1′s. The
geometric shapes used to store data
also included Textures and Diagrams.
Development
Mr. Sainul Abideen, a Computer
Applications student of MES college of
Engineering – Kerala, India has
designed this Rainbow technology.
His design combines various
techniques to create an unique one.
Storing the data as geometric shapes,
we can compress data in 450 sheets
of plain text into a 1 inch square. Also.
the bits and bytes of a 45 second
audio clip can also be compressed on
to a A4 sheet. Based on the sampling
frequency, depth of bit and
compression of audio, the size of the
45 second audio clip can vary from
few kilo bytes to few mega bytes of
data.
The highly advantageous thing with
the Rainbow Technology is that, the
same principle can be extended up to
256 GB of data by using specific
materials and devices.
Rainbow Versatile Disc (RVD)
Data from 90GB to 450GB can be
stored in an RVD, which is 131 times
the capacity of a normal CD. RVD
supports the data in any format like
movie files, MP3 files, picture files,
data files, etc. Special drives need to
be developed in order to support
RVDs. A method called “Vertical
Lining” is applied in RVD.
How it’s done?
In Rainbow technology, the data in
any format termed ‘rainbow format'
has been designed in such a way that
it can be printed out in the form of
images. The data is converted to
rainbow format on the basis of
Rainbow Algorithm. Trigonometric
forms like circle or square, certain
color combinations and certain other
forms are being used. Each
trigonometric form, color
combination represents a complete
pattern.
Most modern technologies like image
processing, pattern matching, etc. are
used for the purpose. The data which
gets converted into an image form is
then printed on paper or any other
thing. This is how the data storage is
made possible. When the steps are
reversed, the rainbow picture is
converted into data.
This is how it’s done!
Although environmental light
differences and color shading is a
problem, it can be overcome up to a certain extent by using efficient
mapping function. Each rainbow
format contains a header, body,
footer, parity, Rainbow boundary
mapper, etc. Header contains the
measurement of the rainbow picture, the algorithm that is being used, etc. It
also contains an efficiently-designed
error checking system.
Pros
CDs are made using Poly
Carbonate which costs about Rs.
400 to Rs. 450 per kilogram and 16
Grams of Poly Carbonate is needed
to make a CD. But the RVD which
offers 131 times storage capacity
than the CD can be made from
paper.
It is highly portable and bio-
disposable.
Cons
Since it is made of paper, it can be
easily destroyed.
A scanner can reliably distinguish
256 unique colors and the scanner
which can distinguish 1,440,000
colors is costly.
Final Words…
Technologies like these will drag us
more towards it. In future, we will see RVD’s replacing DVD’s and Blu Ray Disks as the major storage device. To do that, it has to overcome it’s shortcomings. Let’s hope this environment friendly technology comes into our everyday computing life.
