Physicists at the Technical University of Denmark, otherwise known as DTU designs their own vinyl record disc that is only 40 micrometers across when measured. It plays the first 25 seconds of Rocking Around the Christmas Tree and it is now the smallest vinyl that has ever been recorded globally. The miniature version was cut using Nanofrazor technology, which is a brand-new nano-sculpting machine that the school had recently acquired.
Professor Peter Bøggild explains that “I have done lithography for 30 years, and although we’ve had this machine for a while, it still feels like science fiction. We’ve done many experiments, like making a copy of the Mona Lisa in a 12 by 16-micrometer area with a pixel size of 10 nanometers.”
