Source : DigitimesIn order to show the world the potential evolution of Blu-ray, Pioneer displayed a functional prototype of a Blu-ray reader able to read media containing 16 layers of 25 GB of data for a total of 400 GB.
According to Pioneer, these disks would be readable on current readers (certainly an update of their firmware would at least be needed). Already Pioneer envisages to reach the industrial stage in the next two years. It will be necessary to wait until 2010 to 2012 to have inscribable media and engravers of 400 GB capacity while one could reach TB in 2013.
