style=" mso-ansi-language: EN-GB">‘“ 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).

style=" COLOR: black; mso-ansi-language: EN-GB">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. style=" mso-ansi-language: EN-GB">

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.” style=" mso-ansi-language: EN-GB">

Sets The Standard For Blu-ray Disc’s Future style=" mso-ansi-language: EN-GB">

style=" COLOR: black; mso-ansi-language: EN-GB">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. style=" mso-ansi-language: EN-GB">

Advancements Unlock Blu-ray Disc’s Potential style=" mso-ansi-language: EN-GB">

style=" COLOR: black; mso-ansi-language: EN-GB">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. style=" mso-ansi-language: EN-GB">

Technologies Make Bare Blu-ray Disc a Reality style=" mso-ansi-language: EN-GB">

style=" mso-ansi-language: EN-GB">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, 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.

style=" mso-ansi-language: EN-GB">DURABIS
increases the scratch resistance of Blu-ray Disc media by a factor of 100 in
comparison with non treated disc surface, as demonstrated in rigorous testing.
Because the DURABIS coating technology rapidly discharges static electricity,
the discs also resist the accumulation of dust. 

style=" mso-ansi-language: EN-GB">Specially
formulated for Blu-ray Disc media, DURABIS2 is a hard coating technology. TDK
pioneered hard coating technology, and its DURABIS2 is the ultimate protective
coating for Blu-ray Discs.

style=" mso-ansi-language: EN-GB">As a
member of the Blu-ray Disc Association Board of Directors, TDK has played a key
role 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.
