At the City College of New York, they are experimenting with storing data in three dimensions using lab-grown diamonds and LASERs. Usually, diamonds that have few flaws are more valuable. But in this application, the researchers exploit the flaws to store information. Optical memory that uses a volume instead of a surface isn’t exactly new. However, it is difficult to use these techniques in a way that is rewritable. Diamonds are a crystalline structure of carbon atoms. Sometimes, though, a carbon atom is missing from the structure.
