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.

Western Media should be picking this article up soon.

I like. Imagines Star Wars movies on 200gb discs each.

EDIT: I mis-worded the title. I don't mean to assume that all player will play the disc, but that it's possible. <C'mon, it's 5am here> :lol

Coolness factor: through the roof.
Actual number of TV sets than can display 4K * 2K images: zero, zip, nada.

 

[OverHeat]

damn!!!!!! impressive.

 

[mrkgoo]

Is that like 4 layer =100G, with double side 200G? OR 200G single side?

Don't know. The layers are much closer than DVD or HD DVD so they are able to achieve this. I think the public test was done on a 100gb disc, but they claim that 200gb is also something they are working on.

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

If some parts of the optics were modified, doesn't that suggest a hardware modification was required?

This may be possible just with firmware (going forward, if not now), but for now that point would seem to be important to clarify.

 

[The Faceless Master]

i was like "WOW" until the whole part about some of the optics modified...

then it became slightly less impressive...

I somehow fail to realize the difference to a 50GB Blu Ray or 30GB HD DVD (well, the production costs are a lot higher...).

 

[deadhorse32]

OMG 2160p just around the corner

 

[Suikoguy]

I think 50gig is enough for movies from what I can tell, but this would be useful for TV Seasons.

 

[Inspirius]

Looks like a very neat piece of tech. I'm just trying to imagine what would be required to decode the 64mpbs stream, given that you need pretty much top-end hardware for today's 16mbps streams.

Possibly an interesting technology for digital cinemas?

 

[AlphaSnake]

Out of sheer curiousity, would this be at all possible on HD-DVD?

 

[nelsonroyale]

now put the whole series of one piece on an blue ray...it what this was made for


peace

The desperate HD-DVD contingent proudly plodded out their 4 layer (maybe more, I can't remember anymore) 51GB discs at CES this year in an attempt to steal some Blu-Ray storage size advantage thunder . . . oops.

The HDDVD 51GB discs aren't even out of the lab yet as far as I know (and obviously this 200GB quad-layer behemoth isn't either).

 

[seanoff]

If they can get this out of the lab, woohoooo. esp if it can be played on current hw.

200GB should be enough for the next few years.

 

[Shin Johnpv]

The HDDVD 51GB discs aren't even out of the lab yet as far as I know (and obviously this 200GB quad-layer behemoth isn't either).

And has blu-ray managed to get their 50gb dual layer discs out of the lab and into massmarket level yields yet? Last I heard the yields were still disgustingly low.

 

[tjhooker]

You heard wrong or you heard way back in 2006 :lol

Over half of Sony's 2007 releases are 50GB.

Fox's (MGM's) Casino Royale release is 50GB AVC

 

[Pellham]

more space is only nice if they put like, an entire tv series on a single disc (like all 6 seasons of 24 on 1 disc), otherwise, it's just a waste.

and of course they won't do that because they want to milk customers of their money.

50gb discs are the norm now. Only movies less than 100min, or low budget will probably use 25gb.

Oh ****, internet spelling ahoy!

what I meant to say was:

wow

 

[BoboBrazil]

Very nice. This opens up some really really cool possibilities...Full seasons of tv shows on one disc, several different versions of a movie on one disc(directors cut, unrated, theater, etc), much more space for ps3 games if the developer chooses to use quad layer...

I think both Blu-Ray and HDDVD allow for the later (several different versions), but they have not bothered yet by doing on the fly scene changes.

 

[aaaaa0]

4 layer (maybe more, I can't remember anymore) 51GB discs at CES

3 layers. 17GB each layer.

Wait, so even Sony has started to finally wean off their mpeg2 fetish for a superior codec at 50GB?

With Casino Royale as one of the titles?! OMG YES!!

 

[Raistlin]

Dude ... the tools weren't available. That's the only reason they stuck with MPEG2.

As far as BD50, they were having yield problems ... but BluRay needed to make its move due to the launch of HD-DVD. It's all in the past now.

 

[Sapiens]

Amazing if possible - like everyone is saying, it would eliminate multi-disc annoyance of the tv season box set.
