I imagined something like this, now it's more clear: it isn't that BD is holographic, BUT they devised an implementation of holographic storage that requires a lot less modifications than before to existing optical drive technology and makes also easier and inexpensive back compatibility.
IMHO this, more than making HVD's road a lot easier, puts it slightly better than on a par with the difficulties met by BD, as it had too a quite inexpensive BC, but it took some time anyway to get inexpensive its new parts too, in this case the hurdles about laser emitters cost are already cleared, but those about the new optics and media are still there, and regarding media, they are bigger than those met by DVD and BD, that were quite linear evolutions from previous optical formats.

that's the point, BD is a TYPE OF holographic disc technology. it is not the same as GREEN based laser holographic technology but it's its own type.

there is no defacto Holographic Type.this is just another way that the Implementation of how each of those optical technology's are used.
