IT media evolves on
a daily basis, developing so quickly that
hardware technology is often in danger of
being left behind. The 1 MB floppy disk
sold 20 years ago was replaced by the 700
MB CD, which in turn was superseded by the
4.7 GB DVD.
This spring, the new “HD-DVD”
and “Blu-ray Disc” media, with
15 GB and 25 GB of capacity in a single
layer respectively, were introduced in the
market. Mitsubishi Kagaku Media (MKM), who
has been a leader in the development, production
and sales of recording media for the last
20 years, discusses the secrets of the development
success..
What
kind of company is MKM/Verbatim?
MKM is a group company of Mitsubishi Chemical
Corporation, and is involved in the development,
production and sales of recordable optical
media. Domestically, our products are sold
under the Mitsubishi brand. Outside of Japan,
they are sold under the Verbatim brand.
The 2005 global shipment report by the Santa
Clara Consulting Group shows that the Mitsubishi
Kagaku Media/Verbatim Group has the largest
market share in both CD and DVD media. This
indicates that we are a strong, well-positioned
brand throughout the world.
Please
tell us about the new HD-DVD and Blu-ray
Discs.
Both formats have three to five times more
storage capacity than a current DVD. They
are next-generation optical storage discs.
The Blu-ray Disc (BD) will hold 25 GB of
data on one side and the HD-DVD will hold
15GB of data (single type media).
All TV broadcasts in Japan will
be digitized by the year 2011 and use high
definition (HD) pictures. However, a conventional
DVD can only store 25 minutes of an HD TV
program.
Storing HD contents will require
higher storage capacities, and these new
types of media will satisfy the requirement.
The HD-DVD and Blu-ray standards have already
been established for both the recordable
and rewritable type of disc. The HD-DVD
and Blu-ray Disc will go into mass production
this year, joining the currently popular
DVD. We expect the DVD to continue to increase
in sales. But, we also know our customers
are awaiting the HD-DVD and Blu-ray Disc,
and we want to respond with both of these
products.

Long-accumulated
dye techology helps assure leadership
in next-generation DVDs
(prototypes shown above) |

From
CD-R to DVD and on to the next-generation
DVD, what are your secrets for successful
product development when demand for products
changes so rapidly?
I believe there are several different factors,
but one of them is the accumulation of basic
technology from the past. The accumulation
of different technologies within the Mitsubishi
Chemical Group has been utilized efficiently;
like dye, which today is used as a recording
layer material for recordable optical media.
The same approach can be seen
in optical technology development as well.
The characteristic of the optical media
is how accurately it records data. The recording
mechanism of recordable media is that a
laser light hits the recording layer consisting
of dye, causing a chemical reaction in the
layer, leaving a bit mark behind. Thus,
the recorded signal quality depends on the
quality of dye itself, especially at higher
speed recordings. Therefore, the chemistry
technologies are key. The recording method
does not change, even if the media changes
from CD to DVD to next-generation DVD. It
is our core technology in dye chemistry
that supports the development of new products.
Technological
capability aside, what are some differences
between you and your competitors?
I believe it is the good combination of
our technological policy of “Something
a bit advanced” and our sales policy
of “Something different.” Our
salespeople look for things that are different
from those of other companies, and our engineers
go above and beyond other companies when
it comes to research. When it comes to next-generation
media, we are the only company developing
both the HD-DVD and the Blu-ray Disc simultaneously.
In the areas of optical recording products
with large capacity, high speed, and portability,
we will continue to challenge ourselves
to develop new media that meets our customers’
needs and to lead the world in this area
of technology. |
