whoa.

I know this was mentioned in some other thread months ago, but 200GB discs would not be compatible in current players correct?

It was my understanding that blu ray was capable of 7-8 layer discs max at the time of it's creation in general, they just haven't released any with more than 2 layers yet. So current players should be compatible with any new disc that comes out.

This would be for storage, not for movie playabck.

I retract my previous statement. This is from wikipedia:

Ongoing development

Although the Blu-ray Disc specification has been finalized, engineers continue working to advance the technology. Quad-layer (100 GB) discs have been demonstrated on a drive with modified optics. Furthermore TDK announced in August 2006 that they have created a working experimental Blu-ray Disc capable of holding 200 GB of data on a single side, using six 33 GB data layers.[2] Such discs would probably not work on today's players, as these devices are only designed and tested on discs that meet the current specification.

Also behind closed doors at CES 2007, Ritek has revealed that they had successfully developed a High Definition optical disc process that extends the disc capacity of both competing formats to 10 layers. That increases the capacity of the discs to 250 GB for Blu-ray compared to 150 GB for HD DVD using the same process. However, they noted that the major obstacle is that current reader and writer technology does not support the additional layers.[3]

JVC has developed a three layer technology that allows putting both standard-definition DVD data and HD data on a BD/DVD combo. If successfully commercialized, this would enable the consumer to purchase a disc which could be played on current DVD players, and reveal its HD version when played on a new BD player.[4] This hybrid disc does not appear to be ready for production and no titles have been announced that would utilize this disc structure.

to not take Wikipedia as a definitive source of information.

The chance of Ritek taking "HD DVD" to 10 layers per side is *zero* unless the HD DVD specification is completely re-written. There is absolutely no way that an HD DVD disk can be made with 10 layers on a single side without completely changing the optics (numerical aperture, wavelength or both), changing the response methodology, the layering technology and/or requiring a hard coat like Blu-ray.

With 200GB I wonder if Japan would be able to put their need "16 times better resolution than 1080P" and "22.2" sound on that?

Good work Hitachi, BUT TDK WAS FIRST

Not that it matters, its all Blu-ray

[movies3]

wow 200gb, geeze i could put all my pictures/songs all on one disc from my computer sweet

[j_rocca42]

Dang! with that much storage space I could back up my whole HDD on one disk!!!!

I'd imagine they would if you could get a firmware upgrade..
