Storing Data In Plastic Using Blue Light - New Technology

Mar 8 2004

Researchers at the University of Pisa in Italy have used a polymer thin film and polarized blue light to store large amounts of data in a very small space.

Using a near-field scanning optical microscope they found a nanosized dot polarized blue light shining on a polymer caused the polymer molecules to change shape and align themselves. By equating aligned and unaligned molecules as binary 0s and 1s it could be possible to store digital information at roughly a trillion bits per square inch. That’s about 200 times more compact than current DVD technology.
