Pioneer Ups The Blu-ray Disc Ante Again
Apparently, producing a 16-layer optical disc capable of storing 400GB of data wasn't good enough for Pioneer. Roughly a month after it announced the feasibility of creating such a Blu-ray disc, Pioneer upped the capacity to 500GB in a presentation at the International Symposium on Optical Memory and Optical Data Storage in late July. Pioneer states that by using proprietary technology and stacking layers of alternating thickness, it can reduce "interlayer crosstalk" on disc, thus making a 20-layer optical dic possible. Current Blu-ray discs come in single-layer 25GB and double-layer 50GB options. The goal is now having 20-layer discs ready between 2010 and 2012.
