High Defi nition Media
With less than 10 years since the debut of the DVD format, the ‘Next
Generation’ of optical media is already here and the demand for High
Defi nition (HD) home entertainment is on the rise.
About Verbatim
Verbatim is a subsidiary of
Mitsubishi Kagaku Media, based in
Japan. Mitsubishi Kagaku Media’s
wide-range of operations makes it
one of the leading chemical companies
in the world.
Mizushima Research Centre
Mitsubishi Kagaku Media’s pioneering
strength is visible in its products, for which
the research and development is carried
out in the Mizushima Research Centre.
The company also has strong relationships
with the major hardware manufacturers
in the market. These two strengths
benefi t Verbatim by ensuring not only the
latest technologies and products fi rst to
market, but also that optical discs bearing
our brand are the standard that many
hardware companies test their recorders
on, making our discs superbly compatible.
High Defi nition Television provides an unsurpassed picture quality and a
remarkable high-end surround sound. With the superb resolution, dynamic
contrast, vivid colours and remarkably clear sound effects, high defi nition
brings an additional dimension to your visual entertainment.
With the expected growth of HDTV, there is a consequent growth in
the recording of the HD television programming. Recording 2 hours of
standard defi nition television in standard DVD quality requires a full 4.7GB
DVD disc. High Defi nition content – with its increased resolution and
digital sound tracks requires an ever greater amount of storage capacity.
Verbatim’s Blu-ray discs range from 25GB to a massive 50GB which is more
than enough HD storage space.
What is Blu-ray?
Blu-ray discs (BD) get their name from a combination of the words blue and optical ray. The format was developed
by the Blu-ray Discs Association (BDA), which is made up of a group of leading consumer electronics, major fi lm
studios and PC companies, including our parent company, Mitsubishi Kagaku Media. Verbatim, as a subsidiary of
MKM, has therefore, fi rst hand access to the latest in Blu-ray technology.
Our Research and Development team enables us to be at the forefront of Blue Laser Technology and and we are
currently looking into producing 6x speed discs and quad-layer 100GB capacity discs.
The Blu-ray disc’s higher storage capacity is enabled by a blue laser that has a shorter wavelength than the standard
red laser used in CD (780nm) and DVD (650nm) technology. Blu-ray disc utilises a blue laser with a wavelength of only
405nm combined with a strong lens system with a numerical aperture of 0.85. This results in a ultra-small laser spot
which allows writing smaller data pits which increases the amount of data on the disc. Due to the small data entry spot
on the disc surface hard coating is needed on Blu-ray discs.
