Pioneer Creates First 16-Layer 400GB Blu-Ray-Compatible Optical Media
Pioneer created the world's first 16-layer 400GB optical disc prototype. Each layer is capable of storing 25GB of data - the same as a single-layer Blu-ray. So far, the prototype can only be read, but the company claims its technology allows creating writable media as well.
In multi-layered media it's hard to obtain clear signal from each layer, because of other layers' influence and power losses at transmission. Pioneer managed to solve this issue by means of their DVD expertise.
Since the prototype requires a read head similar to those used in Blu-Ray drives, the company states that they can provide compatibility with Blu-Ray media.
Pioneer will provide more details on this technology at ISOM/ODS2008 starting on July 13 on Hawaii.
