TDK develops 1TB optical disc, leaves other optical storage feeling emasculated

We’ve heard about 1TB-sized optical discs in the past, but TDK has now revealed a 1TB monster of its own at CEATEC. Unlike existing Blu-rays which use four recording layers at most, TDK’s creation features 16 layers on both sides of the disc, each capable of storing up to 32GB apiece. If you’re keeping track of the optical storage arms race, that’s seven more gigabytes per layer than Pioneer’s 400GB and 500GB disc achievements made back in 2008. TDK’s prototype also has the potential to leverage existing Blu-ray technologies, since it’s made from a material already found in BDs and shares the same beam aperture. On the down side, the current version’s recording layers measure 260μm – that’s more than twice as thick as its Blu-ray counterpart – and causes aberrations in today’s fat-layer-hating optical lenses. Outside of its Biggest Loser qualifications, though, TDK says “its commercialization depends on disc manufacturers.” Considering the company has yet to sell the 10-layer 320GB discs revealed at CEATEC 2009, however, we’re doubtful this 1TB improvement will hit stores anytime soon.

I doubt we’ll see these on the market anytime soon, but still, it’s cool to see companies pushing the boundaries.

Wonder which Aberration it is refering to ! a reason for no more news !!

There is something that is needed and is the reason not much is been done for bd. I did look at bd and seems to have stalled in greater write speed and little cost cutting of competitors.

Something has tobreak, something better that the whole optical industry moves on to. With hardware and discs produced at rates like that of cd and dvd that was. Like everyone just need the so called impossible. Large size disc storage, ever increasing write/read rates updatined seemingly monthly. Good strategies for perfect discs. Last but not least cheap quality long life discs. Or at least most of the boxes ticked.

Ok old post but still the only one that is relevant so far in terms of size. Even pioneers 400gb i would be interested. Would buy today if ticked the boxes above. Blu-ray not so interested since i rember it was bd or was that hd that said 250gb possible. Not read anything of that since for a long while.
