Physicists at Imperial College London are developing a new optical disk with so much storage capacity that every episode of The Simpsons made could fit on just one. Speaking at the Asia-Pacific Data Storage Conference 2004 in Taiwan today, Dr Peter Török, Lecturer in Photonics in the Department of Physics, will describe a new method for potentially encoding and storing up to one Terabyte (1,000 Gigabytes) of data, or 472 hours of film, on one optical disk the size of a CD or DVD.
