TDK sent out a press release this morning announcing that they've developed a blue laser technology capable of storing 200GB of data or 18 hours worth of high definition video onto a single disc.
TDK, a world leader in digital recording solutions, has reached a landmark in the development of recordable blue laser technology, 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.
