Interesting new technology could increase BD capacity

"So it turns out that Sony did something right and it, along with a large consortium of supporting folks, won the format war. Blu-ray is now the HD disc format of choice, but even so, the data storage capability won't keep users happy indefinitely. Some recent research from Northwestern University shows that much higher storage densities are possible using technology based on existing optical media."

"Two big questions remain: how much more data can be stored, and can the reader be be scaled down? If scaled directly, the pits would be approximately 50-80nm long, making the per-layer capacity a factor of two larger than current blu-ray discs. However, the depth encoding could easily provide another two to four times the capacity. Furthermore, this is the first experiment, so we can probably expect another factor of two to four from lessons learned during the development process—the optimist in me says that this could give us 30 times more data than a single layer disc."

They can call this SuperBlu...
