TDK ANNOUNCES BLUE LASER DISC TECHNOLOGY TO SUPPORT 200GB CAPACITY
– Media Pioneer Achieves Massive Capabilities
for High Definition Blue Laser Technology –
GARDEN CITY, NY, August 31, 2006 – 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.
Bruce Youmans, TDK Vice President of Product Research & Development,
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 is affirming the company's position as a true pioneer in advancing
the capabilities of optical media."
TDK Sets the Standard for Blu-ray Disc's Future
TDK's research and development efforts are achieving unprecedented capabilities
for next generation optical media. The company's advanced material science
played a key role in enabling the development of 200GB blue laser disc technology.
The company'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 Advancements Unlock Blu-ray Disc's Potential
TDK technologies are redefining state-of-the-art optical media specifications
and performance. 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.
TDK Technologies Make Bare Blu-ray Discs a Reality
Because Blu-ray Disc media's data tracks are quite narrow even in comparison
with DVD media, precise, stable interaction between the laser and the recording
material is especially critical to ensuring error-free recording and playback.
That's why TDK developed DURABIS 2, an innovative hard coating technology
that makes bare Blu-ray Disc media a reality by protecting the disc surface
against common contaminants such as scratches and fingerprints.
DURABIS 2 increases the scratch resistance of Blu-ray Disc media by a factor
of 100 in comparison with a non treated disc surface, as demonstrated in rigorous
testing. Because the DURABIS 2 coating technology rapidly discharges static
electricity, the discs also resist the accumulation of dust. TDK pioneered
hard coating technology, and its DURABIS 2 is the ultimate protective coating
for Blu-ray Discs.
As a member of the Blu-ray Disc Association Board of Directors, TDK has
been a leader in the development of Blu-ray, the next generation optical
media format that will not only change the way we experience home entertainment
and computing, but will also create unprecedented business efficiencies.
TDK Corporation (NYSE: TDK) is a leading global electronics company based
in Japan. It was established in 1935 to commercialize "ferrite," a
key material in electronics and magnetics. The company today is a leader
in the development of next-generation technologies such as Blu-ray Disc
recording media, an optical disc ideally suited for high-definition video
recording. TDK offers a full line of recordable DVD and CD media, digital
camcorder tapes, professional data storage solutions including LTO Ultrium
media, and much more.
