HD-DVD to grow to 51 Go

One of the main limitations of the HD-DVD format is its capacity of 15 Go per layer against 25 for Blu-Ray. To catch up with their competitors, Toshiba will try and have a new format validated by the DVD Forum. Their new medias will sport 3 layers of each 17 Go data, for a total 51 Go amount, a tad more than that of double layer Blu ray ones. To go from 15 to 17 Go, they increased the focus of laser so they could reduce the "holes" size.
Toshiba didn't mention if the current readers will be able to use those medias, be it natively or through a firmware update. If not, the DVD Forum choice might just result in trouble by underming the consumers' confidence in those new formats.
