400 GB Blu-ray 16 layers

**navychop** · 07-07-2008 11:33 AM

Pioneer is developing the 16 layer 400 GB Blu-ray disc. It seems to be compatible with existing players, but to what degree is unstated.

"Pioneer uses a technique that reduces crosstalk from adjacent layers. The result is a 16-layer optical disc that plays high-quality signals from every layer."

More info 7/13/08.

I tried to highlight the link in blue, but that feature does not seem to be working right now.

oh I will be buying one of those.

It'd be nice if this ended up being backwards compatible. Hopefully we'll learn more 7-13th.

Heres the PIO press:

Gee. I might get my Blu-ray server back up system one day after all.

Man, 400gig discs would sure allow some compression room for movies

. Now we'll all have to by new tv's

A snowflake has a better chance to survive in hell then existing BD players reading anything outside 2 layers on any disc: the OPU is not capable of anything else (and can't be made using software only). Backwards compatibility means new players will be capable of reading old 2-layer BD discs. Just like today's BD players are backwards compatible with DVD, i.e. capable of playing DVDs.

The chance to see those new 400GB discs/players outside engineering samples is even lower than that snowflake chances for success...

And before you ask, yes, it's my opinion...

I'm pretty sure they mean current players will be able to read two of those layers, not all 16. And what you said about future players.

Perhaps BD 3.0. 2 copies of a movie could be put on the BD. One for the old 2.0 and lower BD players, and perhaps deeper color depth and/or higher resolution put in a few of the new layers. New players could read the new layers, and the old player continue to work.

But, I somehow doubt they will ever do anything practical like that. I do not think that the studios will go for 4k resolution with 32 bit color depths/channel.

You said the magic word.

Practical, and what you just described probably won't happen for a long time if ever.
