| Mitsubishi Kagaku Media Co., Ltd. |
|
(TOKYO, JAPAN) Mitsubishi Kagaku Media Co., Ltd. (MKM) today announced the world's first dual layer DVD-R disc made to DL standards to be launched this spring.
"Sales of DVD
recording drives
show tremendous
increases worldwide,"
says Shigeru
Tamura, MKM
Chief Information
Officer. "And
industry estimates*2
put demand for
DVD discs in
2005 at some
2.5 billion
units, which
is a year-on-year
increase of
79%." As users
record more
images and movies,
data density
increases and
people ask for
greater capacity
DVD recording
discs. To meet
this demand,
MKM launched
the world's
first double
layer DVD+R
discs in May
2004, which
were well received
in the market.
Now, MKM will
be the first
one to launch
a single sided
dual layer media
in the DVD-R
format, which
is the most
popular format.
With development of this new disc, capacity of DVD-R discs is now double*3 that of conventional discs of this type. When using these new discs in compatible DVD drives, not only large amounts of data can be recorded continuously on the discs, but also the discs can be used in conventional DVD players of PC DVD-ROM drives to playback the recordings.
NOTES:
*1 As of February 16, 2005
*2 Japan Recording-Media Industries Association
*3 Compared to conventional DVD-R capacities of 4.7 GB, MKM's new disc offers 8.5 GB capacity.
* Data must be recorded on this product with a single-sided dual-layer DVD-R compatible drive. Other drives cannot be used.
(Characteristics)
Manufacturing of single-sided double-layer discs requires a high level of production technology to lay down the L0 and L1 layers, coat them with recording material, and place spacers between them. MKM uses proprietary DYN-AZO recording material for recording DVD discs, and application of the technology we developed for this organic recording material enabled MKM to develop single-sided double-layer recording media. In addition, as our advanced stamper technology, combined with ultra-precise substrate molding technology, achieves high writing speed and low error recording for superior recording and playback compatibility.
