while it's an amazing technological achievment...I guess it's too late for optical discs

And we care why?
1) These discs will be over priced
2) It'll require a new player/ROM device to use them
3) BDA is unlikely to spec these for movie play back usage due to compatibility issues
4) Drive storage is far cheaper than all disc media and its 100% re-usable with a far lower failure rate.
It’s nice and all to see someone other than your standard Philips/Sony/Panasonic developers taking interest in the development of this technology, but I think someone needs to face the fact, further development of Blu-ray storage technology is a pipe dream connected to the cesspool that is development research losses. BDA and its technology developers should stop throwing money into the further development of the laser and disc technology because it is working fine the way it is and the technology is finally coming down in price, adding new technology into the mix is just a waste of money at this point with the potential usages becoming fewer and fewer as other technologies emerge.

The laser is for BURNING.
Additionally, who said it wouldn't work on current BD players?
NONE of that was said, and its way too early to make assumptions.

Well seeing that no disc over 30GB has yet to be approved for usage, even though they've were developed and submited over a year ago, there must be something different with the way the discs work once the D/L barrier is crossed. And its more than just a new laser, it requires a new disc media too.

"4) Drive storage is far cheaper than all disc media and its 100% re-usable with a far lower failure rate."
Ha, that's a good one. I have multiple TBs of music & video and constantly have to replace drives where I almost never have to replace a DVD or Blu-ray. Regarding Blu-ray, since Dec. 2006 I have had ZERO defective BDs while I have had at least 6 HDDs, all 500 GB or larger, fail.
All this talk of the death of physical media is way way way premature.
Until we can get HDDs in 10 TB size or larger there will certainly be a demand for physical media. For a collector it is just to easy to fill up 1 TB of content. And I do so on a regular basis.
As far as cost goes I get blank Memorex BD-Rs for less than $2 per, that's about $80 per TB of storage @ 25 GB per BD-R. I haven't seen a Seagate 1 TB HDD in that price range and am not familiar with many other quality HDDs other than Seagate. I have had many iomega, western digital & the like HDDs fail miserably.
Until the economy rebounds expect the status quo where physical media is still KING.
Hail to the king baby......

Dude, what are you talking about? 50 GB BDs are available everywhere.

I hate to cock block your hard-ons for this technology but...
To change the storage capacity of a disc media one of two things HAS TO occur...
1) The write width has to be decreased... Doing so will allow current media to save more data than it is set up for... problem with this method is old readers aren't set up with lasers which can read the new width, even if the media is compatible with the reader the new width would create cross talk between the individual rings of storage, so without a special device separating the individual rings or a laser the same width as the one that wrote it the data is useless.
2) New media... This does allow more data to be written on a compatible disc but the only way the discs can be read is using a device capable of reading it, even if its extended layers some devices developed for older discs with one or two layers may not be able to read greater numbers of layers, DVD ran into this problem with the D/L DVDs were released, some really early players just couldn't read through to the second layer, but then these players were first gen players, Blu-ray is on "finalized" 3rd and 4th gen players/ROMs, if the media comes out and its not compatible with these players/ROMs consumers will get pissed and heads will start rolling. Also, I know the BR-Roms are certified at 50GB, I was tired and typing quick and typed in the specifications for the obsolete media, but I notice you didn't contradict the fact that the 75GB and 100GB and higher discs developed last year (or longer) have yet to see any approval or market as of yet, theses fabled discs go all the way back to 2006, but have a major flaw to them, they're signal degrades after the first few layers... But who knows Maxell's fabled 200GB disc due out sometime this year, at least in 2007 it was, still has a few months to meet the promised delivery date.
I think engadget needs to spend more time explaining how this kind of technology works and less time reporting unproven technology as news... because some of the readers haven't a clue.

i love the idea of this. but am pretty much disappointed at all the blu-ray companies not making blu-ray recorders for the us market. seems like everywhere but here. as for 100GB discs. could make a great computer data backup disc. ie photography, music and video people would love

You know why these recorders aren't here? Because the DVD recorders got their asses handed to them by DVRs, also the Cable companies don't want them here, one some of the most powerful companies in Hollywood don't want them here, four known culprits... Warner, Universal, Paramount, Sony... one owns a cable company and another has controlling interest in Blu-ray... why don't the studios want them here, because it would allow consumers who know what their doing to take their HIGH QUALITY (sarcasm) HD programing and record them and then not have to buy the DVDs and Blu-ray's when they come out.
