Engineers at Princeton University and Hewlett Packard have come up with a combination of cheap materials that might result in a very small card capable of storing far more data than a CD – the example is a gigabyte of information in one cubic centimeter, about the size of a fingertip. Reading and writing the contents would be similar to current memory cards – no moving parts – but there would be physical changes to the materials, making it “permanent” storage similar to a CDR. Here’s an article about the new invention.
