supersandra writes "News.com reports that companies are exploring how to use molten silicon, designer molecules, and even protein globules from cows as data storage media. The media made by Nanochip using molten silicon, called ovonic media, is similar to CDs or DVDs but can store much more data because the tools for reading and writing data could potentially be 25x smaller. Nanochip demonstrated a 1-inch square chip of material that could contain a terabit of data. ZettaCore has created a complex molecule that can retain or release up to eight electrons, exhibiting a voltage level that can be read as data, and thus each molecule can represent 4 bits of data. Another company, NanoMagnetics, uses a magnetic core surrounded by animal protein, and can also achieve a terabit of data per square inch."
