Dang, I dropped the Library of Congress again

Researchers at IBM have developed technology which uses dents in thin plastic film to store information. It’s a bit like the punch cards of computing history, except the dents are 10 nanometers in width. (A nanometer is one-millionth of the width of a piece of paper-clip wire.)

The researchers estimate that with this technology in practical use, a common multifunction digital wristwatch could contain 15 gigabytes of data… that’s about 23 CDs, or 2 or 3 DVD movie discs.
