TDK has reached a landmark in the development of recordable blue laser technology by achieving a groundbreaking capacity of 200GB. Surpassing existing optical media technologies several times over, a 200GB blue laser disc would double the capacity of TDK's existing 100GB Blu-ray prototype. One of TDK's new 200GB blue laser discs could store approximately 18 hours of high definition video (encoded at 24Mbps).

The initial Blu-ray Disc standard allows for 25GB single layer Blu-ray Discs and 50GB dual layer Blu-ray Discs. However, a recent signal processing innovation stretches the physical limits of optical media, realizing 33.3GB capacity for each of the disc's six layers. As with the 100GB disc, and other Blu-ray Disc media, TDK's 200GB blue laser disc is single-sided.

Bruce Youmans, TDK Vice President of Product Research & Development, said in the press release: "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. TDK was the first to develop a prototype 100GB recordable Blu-ray Disc, and yet again, our landmark achievement in creating a 200GB disc is affirming the company's position as a true pioneer in advancing the capabilities of optical media."

TDK's 100GB prototype disc uses four 25GB layers to reach 100GB capacity. For the 200GB technology development, TDK has stretched the physical margins of the Blu-ray Disc format, enabling a disc to store up to 33.3GB per layer while staying within the tolerances of the BD playback specifications.

TDK has already been able to achieve 6x (216Mbps) recording speed on a 25GB write-once Blu-ray Disc prototype.

Είναι 200 GB άραγε αρκετά για HD υλικό;;;:chinscratch: :chinscratch:
