I read over at PC Magazine (via Format War Central) that the BDA is planning to issue specifications for two new versions of the Blu-ray Disc.
The first is a higher capacity writable format while the second is an interesting combination of pressed and writable disc.
The higher capacity writable disc is no surprise since we have seen prototypes of these at CES for the last several years.
The BDXL will have capacity options at 100 GB and 128 GB in writable forms and 100 GB in rewritable form, going beyond the traditional dual layer disc stack to achieve these new capacities.
The hybrid IH-BD will feature a 25GB pressed layer for pre-recorded data and a second 25GB layer that can be written without disturbing the original content.
This will no doubt allow for either the addition of new supplements after the disc has been released or the addition of personalized media to the disc.
Needless to say, current players will not be compatible but as the specifications are finalized, expect future players to be capable of the new formats as well as having backwards compatibility to all 12 cm optical discs that have gone before.
While some may boo and hiss, I think that this is not the last we will see of Blu-ray Disc extensions - watch for faster, higher capacity discs to support 4k2k video in the next couple if years too.
After all, there always has to be something new to make the new Blu-ray players a worthwhile investment.
