If it's just data storage I am not interested. If it can play video, why don't they bring quad-layer discs to market first now and those 16 layered discs by 2010 ?

well i remember hearing they'd never us anything more than 50gb for movies..so who knows if that still holds true or not

They replicate movie discs (manufacture the disc and stamp the content onto it). This is a recordable, which would mean a studio would have to duplicate to use it.

I would have never expected any major commercial duplication (some small run DVDs are duplicated), but then Sony went ahead and announced those CD(-R)s which are burned with a blue-violet laser to reduce jitter (coughing ... BS ... coughing) so who knows.

THIS is what I understood was what Blu-Ray was suppose to be able to do and was one of the MAJOR points of this format!!!!! THIS is what and why I have been waiting and paying attention to this new format since the year 2000 THREE years after d.v.d.s came out. Back when it was called "Multi-Versatile Disc" and being developed by independant people from half a dozen different places on Earth.

I was told my numerous people...if not everyone here for that last couple of years of how stupid I was and out of touch and such a fool for thinking that one of if not THE reason Blu-Ray discs were to be the next format was because of the incredible storage space in terms of how many hours could be put on one disc. I had always understood that one of the MAIN reasons of switching to this format was that they would be able to increase the storage size over time...and in the NEAR future AND keeping this same format so that it would not even have to get a new player! I pray to God that this happens as well as the music industry adapting this new format the sooner the better.

this is cool, on the other hand if it ever shows up (or anything beyond 50GB) I have no idea. On the other hand capacity is not the only metric and unless they increase the bitrate it is relatively useless for movies in my opinion. After all who wants 8-10 movies on one disk (not that I would complain if it happened but how many 10 movie sets are there)?

Try praying to the BDA instead.

I'm afraid your understanding was still flawed. These discs will never be pressed with studio content. Here's what Pioneer has stated, per McBain's links:

"This is a technology exhibit only, and is not being proposed as a candidate for addition to the Blu-ray Disc format at this time. Current BD players and drives would not be able to play/read these discs. Current Blu-ray optical pickup designs could be utilized in new players/drives designed to read these discs. At present, this is a read-only technology. Recordable versions could eventually be possible."

Pioneer's 16/20 layer discs are indeed ROMs.

As some have noted, the replication challenges presented by this new disc format are formidable (e.g., different materials, stacked heterogeneous spacer layers between data layers, etc.) and will almost certainly limit its application to ISOM/ODS events.

As an aside, Pioneer never said these discs were (backwards) compatible with BD-ROM. Pioneer said maintaining compatibility is possible, based on the shared lens specs. The interwebs got a bit carried away with the story, neglecting to note that the readout demo utilized a hardware/firmware modified current gen deck.

Flash memory is never going to get to the low price levels in cost per GB as optical discs. It's always going to be cheaper to replicate discs on a massive scale than sell movies stored on flash based media.

yup, much much more, but this is what happens guy looks at large USB stick that costs less then an expensive BD movie and says "wow one day it will be solid state" and misses that it will never be cheaper then 1$ (which it would need to be interesting) and since the data would need to be DL later the time to fill up that data to the drive would cost a lot, while disk replication creates the data and disk at the same time. That is why duplication (DVD-R) is much more expensive and only for small numbers.
