Thanks to CDFreaks and Clubic:
The French hardware site Clubic has posted information about Sony's upcoming dual layer (DVD+R9), dual format DVD recorder with modelname DRU-700. Writing dual layers will enable the drive to write 8.5 GB on a dual layer DVD recordable where at the moment about 4.7 GB can be written to a DVD recordable. The DRU-700 writes dual layer DVD recordables at 2.4 speed and normal DVD+R and DVD-R discs are written at 8 speed. Writing DVD+RW and DVD-RW discs will be at a maximum of 4 speed.
Besides writing DVD recordables the drive is also able to write CD-Rs. It is able to do this at 40 speed and it writes CD-RW discs at 24 speed. Reading back of CDs is performed at 40 speed while the drive reads back data from a DVD at a maximum of 12 speed.
The drive will be delivered with Nero and should cost about 199 EURO. An external version of the drive will also be available at 299 EURO.
