TDK Announces Blue Laser Disc Technology to Support 200GB Capacity; Media Pioneer Achieves Massive Capabilities for High Defini

Business Wire
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. About TDK
