Better Holographic Data Storage

Pinlighter writes "Optical holographic data storage has the potential of providing better storage densities and access rates than the magnetic media used today. However, the technology has problems, mostly because the information tends to get a bit scrambled each time it is reread. According to the link, a group of Japanese scientists have now developed a material which is stable for hours and across multiple rereadings. The material also allows easy erasure (by UV light) and rewriting."
