Verbatim
has announced that "it is on schedule to deliver industry's first Double-Layer
DVD+R (DVD+R DL) discs". The first 8.5 GB DVD+R9 media should ship this spring
and will be 2.4x speed discs according to Verbatim.

The first recording
layer of the Verbatim DVD+R DL disc is semi-transparent, providing enough
reflectivity for writing/reading data on the first layer, yet transmitting
enough laser power to read/write on the second layer by refocusing the
laser. In addition to optimizing layer reflectivity, new Metal Azo
recording dyes were developed by MKM for each layer to optimize parameters
such as signal amplitudes and power margins and ensure full compatibility
with current DVD standards.
"Compatibility was a top
priority in developing our Double-Layer media," said Tim Clatterbuck,
Verbatim Director of Optical Storage Marketing. "Content developers will
be among the first to make the switch to Double-Layer technology because
multimedia and video files require so much capacity. They can increase
their productivity with the 8.5GB DVD+R media without worrying about
playback compatibility. It will be the same as their 4.7GB discs, just
more capacity."
BenQ/Philips and
Sony have been rumored to launch dual layer burners as early as in April so
hopefully we will be able to burn DVD+R9 discs before the summer. You can find
