Pioneer's 400 GB Blu-Ray Disc Coming
According to Pioneer, Blu-ray technology will be in for a huge upgrade. The firm claims that it has developed a new disc manufacturing technology that will allow up to 400 GB of data to be packed onto a single disc. Sounds too good to be true?
Here’s the real kicker: Pioneer claims that the new 400 GB Blu-ray discs will be fully compatible with existing Blu-ray readers. This means you can go out and buy a 400 GB who knows what, and pop it into your existing drive without a hitch.
The new discs are 16-layer discs, compared with today’s dual-layer discs, and utilize a smaller pitch and beam wavelength. Despite this, Pioneer still claims compatibility—although existing players and records may require firmwares to adjust the pickup.
Pioneer also claims that when these new discs start rolling out, 400 GB Blu-ray burners will accompany them as well. Just imagine what kind of things you can jam onto a disc of that capacity!
I think that it is still coming. I am not sure how close of the upper limit of BR this is, but the holographic disc can take severals Terabytes of content, so it will offer even bigger storage. But if this really work with older BluRay eguipment it does have an advantage!
yeah and its still phisically spinning media so writing 400Gig will take what 2, 3 weeks. I cant wait to fire one of these up on my 1x burner.
B. does this matter if adoptation of Blu-Ray continues to be so miniscule?
C. when they make 400GB blu-ray read/write disks, it will take a LONG to burn the full 400GB with current speeds. a 2x blu ray burner will write to a dual-layer disk in 90 minutes, a 1x burner would take 180. now imagine how slow writing 400GB would be, unless they develop 24x or faster blu ray burners very quickly.
I don't like that optical tech is catching up to HDD tech in capacity. Seems to me that if a cheap renewable 400gig disc can be had for less than a HDD, we havea problem.

36Mbps / 8 = 4.5MB/sec
409,600 / 4.5 = 91022.222 seconds (repeating)
which I believe means that at 1x this disc would take 1.05 days to write (25hrs)
$600 for a dvd anyone?
why would this drive up DVD prices?
Well thats just prototypes ATM, they will be very expensive IMHO.
Also they still cannot compete in size (1 TB drives) access or write speeds or durability.
Sure they made a blunder when they faked the demo on the showroom, but that didn't mean they lied. Now they are marketing the darn thing, only not for consumers though
Such a pity. The approach easily allowed hundreds of layers, meaning gigabytes and terabytes of data. It is also rewritable from the start, and practically scratch-proof (unless the scratch reaches and destroys the flourescing dyes).
*sigh*
