Around 200 billion pages of text could now be stored on a glass plate the size of a compact disc based on a new discovery through nanotechnology.
A team at the University of Southampton has been using nanotechnology to create an amazing new form of data storage (pdf.) With the help of ultrafast laser, data is written into silica glass creating layers of nano-sized dots in five dimensions.
The researchers say the data could last for a million years. Their prototype could be the first record to outlive human civilization. Everything we have learned could be saved forever. It is mind-blowing stuff!!! Regardless of how long it lasts, the method can cram an incredible amount of data into a relatively small area.
By recording data in five parameters – the 3D position of each nano-dot, plus two properties related to how light is diffracted inside the glass – a piece of glass the same size as a standard CD could store around 360 terabytes of information!!!
One terabyte is equivalent to 2,000 hours of audio recorded at CD quality, or 220 million pages of text. The above discovery could be termed as one of the best in the recent past.
