Hitachi demonstrates playback of Quadruple Layer Blu-ray Disc using "normal drive"

- Demonstration is playing a QL Blu-ray disc, switching layer and showing its signal pattern by an oscilloscope
- Each layer has different frequency signal pattern (L0:3T, L1:4T, L2:5T, L3:6T) to distinguish easily current reading layer from other layers
- Reader is not a special made equipment, it is based on Hitachi's commercial BD drive GBW-H10N with modified firmware and some part of optics

All players can perhaps be updated via firmware. It is assumed that the discs themselves can contain the firmware to install to any Blu-ray device, allowing the laser to read all 4 layers. And since Blu-ray has no lag between layer switches, video and audio will be seamless.

Just think of the possibilities...whole seasons of tv shows on one disc, several different versions of a movie on one disc, etc...

By the time I'm 60 I wonder how many times I will re-buy my movie collection.

But for a regular BR movie, there is only so much room you can use. There would be no need to put, Batman Begins on a 200GB disc.

But Prison Break would be great on a 200gig disc. As would the LOTR The Trilogy.

You could get a Sitcom on 2x50GB discs with VC1 or 1x100gb. You'd need a 200gb disc for an hour long show

I think I will use this quote as my sig!

With your permission, of course. Let me know...

Weren't the original 200GB disks based off of 33GB layers?

Sure, I don't mind.

ROFL!! I nominate for quote of the year!! As I looked at the graphs and the 4k2k stuff I thought here we go again....

This is all garbage. We just got 50G disc's up and running and now they want to blow more smoke up our assess with this garbage, Please. This is not needed at this time or in the next 5 years. Hell you have some BD movies now that won't play on BD players with out a firmware update ( Descent ) as well as 50G disc's that don't even have all the extras and langauge options of the regular DVD versions let alone any real next gen bonus content some storage advantage.

Yeah, how are those Weinstein discs playing in your Tosh's?

Digital cinema @4Kx2K is still too far away. Our displays are still a ways off. But if we can get D5 HD onto a 200GB, we'd get 10bit YUV @ 4:2:2.

As far as most are concerned that's as close to digital master for HD res as we can afford without big jumps in display technology.

These are only needed for certain things. You could get a whole season of 24 on one disc, multi-movie collections (Matrix, LOTR, "The Adam Sandler Collection") it could come into use in the not-so-distant future (2-3 years).

Star Wars Trilogy would be nice.

Also, they are useful for storing videos taken by HD camcorders (which has a chance of becoming the next big thing in Japan). People would like to have 20 discs for one year of their baby growing up instead of 100 per year....

how fast those babies grow

This would never work. People won't want to pay the price of a box-set for a single disc. Storage and home-made content is where this could take off.

Hell I'd pay $100 for LOTR Trilogy, all extended editions in High Def with uncompressed Audio.

Or can you imagine. All 6 Star Wars movies on 2 200GB Bluray discs. NICE !

My entire CD collection on one BD-200gb!!! Nice.

Batman Begins was far from perfect using VC-1 at 30GB of space. BB would benefit from a re-encode to 50GB and definately would look superior to even the theoretical 50GB version if it was re-encoded to fit on a 200GB Blu-Ray disc.

Entire seasons on one disc seems to be the best use of the 200GB disc. I would still want Star Wars trilogy on three BD-50's. Unless Lucas uses a 200GB disc and re-encodes the SW films to use up more than 50GB for each films video and audio combined..

So when is the 200GB disks coming out? Imagine a video game using all 200GB?

wow! I'm really impressed they were able to get established hardware to read the medium properly.

If this really works with all existing players thats fantastic!

I'd want to use the space for QUALITY first and foremost. You could have pro-grade 4:4:4 component and 32 bit color information and zero artifacting with something like that. Perhaps even a real 4k file. Plus, 8 channel LPCM at 24/192 for each channel!. Or perhaps even 10.2 channel LPCM at 24/192! Or if you want even more room for video go with a lossless audio codec instead of LPCM with the same specs. as above.

I would HAPPILY pay the price of a box set for a single (200gb) disk. In fact, I'd pay a small premium. There is nothing more obnoxious than wanting to see a particular episode of the Simpson's season 7, and not remembering which episode is on what so you leaf through your booklets, trying to find the printed list that is no longer kept with the box set (because multiple people have used it) and eventually just inserting random dvds until you find it (this is life-endingly obnoxious if you do it with the A1's molasses-like load times).

I realize that marketing dogma is that people are more likely to spend money on sets containing lots of disks, but I think that a simple education campaign would easily persuade customers to the benefit of having an entire trilogy and/or sitcom season on a single disk.

lol HD-DVD will probably die off before we even see the 51 GB disks go into production let alone the 150GB 10 layered disks.

could see these for 3D movies; upcoming star wars trilogy rerelease; cameron's Avatar...

200GB should be good for possible 2160p releases someday I would assume. It would certainly keep BD viable if TV's supporting such higher resolutions came out in the next 5 or so years.

Wobulated 1080p-chip DLP's perhaps to double the resolution.
