Pioneer Preparing a 400 GB Optical Disc
Pioneer is preparing what it claims to be a 16-layer optical disc. Though no information about its format have been released yet, Pioneer claims each layer of this disc can carry the same amount of data as a Blu-ray disc layer. With 16 such 25 GB layers, that comes up to a huge 400 GB capacity, enough for..err..whatever you want to do with all that space.
The disc however seems to have problems relating to each layer interfering between the surface of the disc and the one the player is trying to read from. Pioneer said it applied an array of optical and signal processing techniques to create a "16-layer optical disc that can play back high-quality signals from every layer".
Apart from having similar layer-sizes to the Blu-ray disc there are other features that make this disc format suspiciously similar to that of Blu-ray, such as the specifications of the lens. Pioneer is quick to defend saying that it's just so the player could maintain compatibility with Blu-ray discs.

It's not of much concern if the technology to make and use a 400GB OD is built off of BR, as Pioneer have the technological rights to do so.
It's been surprising to me, though, that Pioneer and Sony have been able to cooperate in the BR realm for so long, as the two companies don't typically see eye-to-eye.
This example of what they're capable of, IMO, only proves to me that Pioneer is still a major player in the digital media market and will continue to help push boundaries even further.

I my country I don't see any blanc double side or double layer disc to buy. ... the local authority steel demand that all the fiscal data to be send to paper or floppy disk.
BD uses a scratch resistant coating, but because of the higher data density smaller scratches have far more of an effect. 4GB - 25GB, means that a scratch 1/5th the size will take out the same amount of data.
i personally would rather back up my hard drive to a disk rather than other hard drive
OHHHH some company even still use huge magnetic tapes to back up
that holographic disk i heard bout in early 2007 sounds like the next big thing to me
