Pioneer Develops 400 GB Storage Disc7 Jul, 2008 By: Chris Tribbey
Pioneer Corp. has successfully developed a 16-layer, read-only optical disc capable of holding 25GB per layer, or 400 GB total. The Tokyo-based company will present the research details at the International Symposium on Optical Memory and Optical Data Storage event July 13 in Hawaii.
“This multilayer technology will also be applicable to multilayer recordable discs,” the company said in a press release. “This development has bolstered Pioneer's confidence in the feasibility of a large-capacity optical disc, which is expected to become necessary in the near future.”
The company said it had solved problems with reading all the data burned on so many layers. Typically, so many layers make it difficult for the data to be clearly read by optical players. The company also said the new discs should remain compatible with current Blu-ray technology.“Since the optical specifications of the objective lens … are the same as those for the existing BD discs, it is possible to maintain compatibility between the new 16-layer optical disc and the BD discs,” the company said. “The 16-layer optical disc technology, capable of storing much more data than the conventional discs on one disc, will greatly reduce the number of discs to be used and therefore contribute to the conservation of resources.”
