[TS]Pioneer reveals 400GB Blu-ray disc

post #1 of 18
Thread Starter 
Quote:
A standard Blu-Ray disc might have enough storage space for a high-definition movie, but Pioneer is taking optical storage capacity to the next level by announcing “the world’s first” 16-layer disc capable of holding a massive 400GB of data.

Interestingly, the new discs are similar to Blu-ray disc technology (each of its layers have the same 25GB capacity) and slight changes to the hardware on a Blu-ray drive would allow the new Pioneer discs to be used on one. The disc developed so far is only read-only, and no mention has been made of writable 16-layer discs yet. Little else is known about these discs, though more information is expected at the Symposium on Optical Memory and Optical Data Storage 2008, which is being held on the 13 July in Hawaii.

Well, which is it...is it Blu-Ray, as the title suggests; or is it similar to Blu-Ray, as the article states? I mean, HD-DVD was similar to Blu-Ray.If you have to change the hardware of the existing Blu-Ray players to read these discs, then it's not Blu-Ray.

If I were Sony, I wouldn't let this get out branded as "Blu-Ray" unless it's fully compatible. It's not like Blu-Ray is lighting up the sales charts; the last thing they need is for more format FUD to be introduced by Pioneer.

Maybe it will at least move down the price of current blue ray blank disc.

If they aren't compatible with the current Blu-ray players(as in hardware), then I won't really think it's a Blu-ray disc.

It is most likely the ability to be able to re-focus the laser to the required layer in the disk to read the data that current players lack.

With the speeds they write, it's not exactly easy. They need to pick up the write speeds to that of a normal CD, if not DVD, and doing that would cause instability to the disc itself. That, and writing 400GB would take about 8 hours, and after, you wouldn't be able to touch your disc drive without the feeling your hand would be heavily burnt from the use of the drive.

To answer your question, look at ExtremeTech's version of the article:
http://www.extremetech.com/article2/...129TX1K0000532

It would appear as though everything is the same (the laser head, the optics, etc.). Only the materials put into the disc are the different so as to mitigate cross-talk between layers and allow for clean reading of the information on each layer.

This being compatible with current technology is great if you have a player with updateable firmware, such as the PS3.

As for your argument about Sony not letting this be branded as Blu-Ray if it is not fully compatible with what is already out there, I would agree that it is the best way to do things but don't forget that Sony hasn't cared in the past if new features are compatible with existing technology so why start now?
