Pioneer Develops 16 Layer 400GB Optical Disc

If you listen to me I'll happily tell you a million and one reasons why the optical disc is dead, but then things like this come along...

Pioneer - famed for its stringent Blu-ray support - has come up with the world's first (that phrase again) 16 layer optical disc holding a monstrous 400GB capacity. Interestingly, Pioneer also says the breakthrough (which holds the same 25GB per layer storage as a Blu-ray disc) could be made compatible with the HD format winner.

Explaining the challenges behind the breakthrough Pioneer explained:

"For multilayer optical discs, it has been difficult to obtain clear signals from each recording layer in a stable manner due to crosstalk from adjacent layers and transmission loss. Utilizing the optical disc production technology that it has developed in the DVD field, Pioneer solved these problems by, among other things, using a disc structure that can reduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can playback high-quality signals from every layer."

Full details of the research involved in this tech will be presented at the verbosely titled International 'Symposium on Optical Memory and Optical Data Storage 2008' (ISOM/ODS2008 for short-ish) to be held in Hawaii from 13 July.

Quite what this means for Blu-ray is unclear at this time as existing players would almost certainly be unable to handle the format so it could once more split a format already struggling to unify public opinion. That said, don't expect it to start turning up on shop shelves anytime soon.

Me, I'll still tell you the optical disc is dead. I'd argue who wants to store so much data on a medium that can be destroyed by loose keys...?!

I like how they (randomly/corporately?) chose Hawaii for their symposium. Surfs pretty good this time of year too.

Perhaps they should rename the event 'ho&#8216oholo lolouila', which, roughly translated means 'computer decision'?

Mine's the grass skirt and pi&#241a colada...

Oh lord here we go again, lets just leave it at Blu Ray for now please at least give it a couple of years.

Hell, it's never too early! I was backing Blu-Ray from the outset because I first heard about it 7 years ago! First I heard of HD DVD was when the "format war" started getting publicised...

Bet you there's a 16 layer format war in 5-ish years time, the rival format comes out of nowhere, and I bet this Pioneer one wins out. Either that or holographic storage is the next big format thing - and the rival format comes out of nowhere and the originally publicised one wins out...
