TDK Announces Blue-Laser Disc Technology To Support 200GB Capacity

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, the latest signal processing innovation stretches the physical limits of optical media, holding 33.3GB on 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.
Taro Ikushima, Product Manager Commercial Products Europe, said: “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 further cements the company’s position as a true pioneer in advancing the capabilities of optical media.”
TDK’s research and development into new technologies is bringing new possibilities to next generation optical media specifications and performance. The company’s advanced material technology was influential in playing a key role in enabling the creation of the 200GB Blue-Laser Disc development. The company’s 100GB prototype disc uses four layers of 25GB to reach 100GB capacity. For the most recent 200GB technology development, TDK has stretched the physical margins of the Blu-ray Disc format to hold up to 33.3GB per layer while staying within the tolerances of the BD playback specifications.
TDK technologies are redefining state-of-the-art optical media specifications and performance. The company’s advanced material technology played a key role in enabling the creation of the 200GB Blue-Laser Disc. Additionally, TDK’s new inorganic film formulation provides absolute stability with narrow track pitches and high recording densities, such as those employed by the Blu-ray Disc format. The formulation’s optical qualities are so stable that TDK has already been able to achieve 6x (216Mbps) recording speed on a 25GB write-once Blu-ray Disc prototype.
Specially formulated for Blu-ray Disc media, DURABIS2 is a hard coating technology. TDK pioneered hard coating technology, and cliams DURABIS2 ia the ultimate protective coating for Blu-ray Discs.
