Pioneer develop new 400GB optical media
Each disc contains 16 layers of 25 Gbytes each, Pioneer said. For now, the disc is read-only. Pioneer solved these problems by, among other things, using a disc structure that can reduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can play back high-quality signals from every layer, the company said in a statement Monday.
Pioneer will present the details of this research at the International Symposium on Optical Memory and Optical Data Storage 2008 (ISOM/ODS2008) to be held in Hawaii from July 13, the company said.
