Pioneer Pioneering Blu-ray

Post by Steve Farrelly @ 05:05pm 03/12/08 | 32 Comments

At the IT Month Fair currently underway in Taipei, Pioneer showed off their own spin on Blu-ray technology with a 400GB capacity multi-layer read-only disc.

The new optical storage update, utilises 16 separate layers on a single side of the disc, each layer allowing 25GB of storage data. Do the maths. Normal Blu-ray discs use reflective metallic layers while Pioneer's number has come up with a new layer technology through dielectric material.

According to reports, the new disc is completely readable in current Blu-ray models as well, offering more of an expansion, rather than reinvention (good news for consumers also).

nice. 400gb should be enough to stave off the next incarnation for a decade or so.

At the moment it's only read only. It's still a step in the right direction they're expanding storage to this capacity in the first place

16 layer Blu-Ray discs sound totally affordable, especially given that dual-layer DVDs are still about $5 each.

I bought a 3-pack 2 months ago for $4, verbatims in jewel cases and everything.

Are you serious? I've -never- seen them that cheap before (though that's still overpriced, imo). Where was that?

If they are only read only, then how do you get data on them to read eh EH!? CONSPIRACY!

SHENANIGANS!

Something must be able to write to them, making the discs writable! HA!

Every time they make a disc, it has random data on it. So they have to go through TRILLIONS of discs until it just happens to have the data they want on it. That's why blu-ray discs are so expensive. Duh.

And, that's pretty cool - hopefully 400G is enough to fit whatever the next gen "super-HD" media is :)

Manufactured disc aren't written or burnt, they are pressed. Like a vinyl record.

Little addition: When a game goes gold it means the master disc which is made of gold is ready to be used to make press plates from.

Err, Roger lies?

I'm pretty sure its an old throwback to when writable CDs were gold in colour. The 'gold' CD was the final build sent to manufacture.

gone gold.
Makes you wonder how they make that original one though. Vinyl were "cut" using a needle but how the hell would you make the little pits/ridges/whatever on a cd? High powered laser? I'm too lazy to bother looking that up :p

\/\/\/ Yes I know they're moulded but how do the get them there? My guess is a room full of midgets with chisels hammering away at a circle of tinfoil.

CD mastering differs from burning, as the pits and lands of a mastered CD are moulded into a CD blank, rather than being 'burn marks' in a dye layer (in CD-Rs) or areas with changed physical characteristics (in CD-RWs). In addition, CD burners write data sequentially, while a CD pressing plant 'writes' the entire disk in one physical stamping operation.

Buy whatever you need to make the 400gig blueray discs and start a service where people can send you 400gig of stuff and you will burn it.

So wait pioneer made a 400gig disk that is non-writable from the start?

That's like saying we've turned lead into gold but it's highly radioactive so it's worthless.

They would need to release the technology first to be able to read to the discs first for this to work..

what i think they are trying to say is that they would have a different drive that would be able to burn it.. but actually read compatitble on a blu ray player?

SSD will kill all. Once the price of SSD comes down optical media will die. You'll all be off to the video store to borrow your latest HD movie on SSD that will connect to your tv with a usb port.

when i was in jb hifi last they had some 25gb & 50gb blu ray discs, the 50gb was about the same price as buying 2 25gb discs (if not slightly cheaper, was a few weeks ago, all i remember was the 50gb disc was the way to go price wise), so at least unlike with dvds, multi layered blu ray discs are scaling well price wise so far.

as for a 400gb disc, a movie studio could fit a whole season of a HD tv series on just 1 disc, so its read only atm, but thats at least something that would be practical with it being read only.

Mass, i dont know what ssd is (call me sheltered), but another alternative is holographic storage (up to 1.6tb in a few years):
