TDK Develops 200GB Blu-ray Disc

TDK announced Thursday that it had reached a new milestone in data storage on Blu-ray discs, revealing a prototype that can hold 200GB. The disc doubles TDK's previous 100GB prototype and is possible by creating six distinct layers of data, each capable of holding 33.6GB.

The prototype, like all Blu-ray media, is single sided. "The ultra-ambitious technology roadmap for Blu-ray has now been confirmed as realistic, with landmarks such as this proving the long-term value of the format against its rivals," said TD vice president Bruce Youmans. TDK said such high-capacity discs could be commercially available in several months.
