TDK this week confirmed its plan to develop a Blu-ray Disc with a
storage capacity of 200GB. If successful, the company's R&D
effort will yield a disc with four times the capacity of today's
biggest BDs and double the size of protoype next-generation BD-Rs
TDK has already demo'd.
TDK showed off a 100GB BD prototype in May 2005. The 100GB disc
contains four data-storage layers, is recordable and supports a
write speed of up to 216Mbps, double that of 50GB BD-Rs.
It's expected to come to market next year, though with 50GB BD-R
and BD-RE discs not yet shipping - media makers are now starting to
push out single-layer, 25GB product - how soon that will be is open
to question.
The launch timeframe of the 200GB disc - with eight layers,
presumably - is even more uncertain. TDK simply said it was in the
process of developing such a part, and didn't even hint when the
prototype might appear, let alone commercially available product.
