BD-R media: 12x Burning Speed!

Philips R&D engineers have successfully burned a Blu-Ray media at 12x.
This is a real achievement and a record so far. To reach such burning speed, the rotation speed of the media must be 24,000 rpm. So far, media can not stand more than 11,000rpm, due to their physical limits defined by their current polycarbonate-based composition.
So to reach such high burning speed, one has to enhance physical resistance of the media, of course such media will cost much more, making such technology only valuable for Professional backup.
Burning speed for the blue laser-based burner customers market should top at 7x, already a quite amazing speed, as it requires feeding the burner with 32MB/s of data.
One way to go faster would be to have a second blue laser diode, but it will require enhanced burning management systems.
