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.
