TDK Creates 320GB Disc With Blu-ray Technology

TDK Creates 320GB Disc With Blu-ray Technology

TDK has always been one to push the limits. Back in August, we heard that the company's roadmap included 960GB laptop drives and 3.2TB desktop drives. Now, we're also hearing that it's looking to push the same boundaries in the optical media realm. How does a 10-layer, 320GB disc sound? Sounds like Blu-ray whimpering.

Reportedly, the media storage company has already developed a 10-layer disc capable of holding a whopping 320GB, or 32GB per layer. Better still, it's possible to write and read data on and from the disc by using a blue-violet semiconductor laser with an oscillation wavelength of 405nm and an objective lens with a numerical aperture (NA) of 0.85. We know that's probably way over your head, but here's a simple way of thinking about it: that's the same stuff we already use on Blu-ray Discs, so the write/read technology is already out there in the mainstream.



The disc is structured as follows: there's a cover layer, a hard coat layer (which protects from scratches and such), recording layers and a Si-Cu alloy layer. The company has tested the disc and has found it to be reliable enough for commercial use; in fact, it's planning to showcase the disc at the CEATEC trade show in Japan next week. Who knows--maybe digital downloads won't be the death of Blu-ray after all. Sure sounds like it has way more familiar rivals to worry about.

Wow, how reliable are we talking about? Will it be possible to have rewritable discs?

Either way, I don't need a hard drive anymore, just one of these babies and BlueRay-type drive!

It's another reason to migrate towards SSD, with faster performance, less power consumption and greater reliability. No need to have those 1TB mechanical drives with greater storage space offered by drives such as this.

You're forgetting that the disk will also cost as much as those 1TB hard drives. Heh.

One thing people seem to forget is if it's compatible with existing blu-ray players out in the market. I don't think consumers are willing to spend on another blu-ray player for the sake of capacity.

I agree, Kyouya. We know that Blu-ray writer adoption has been pretty dismal on PCs; I think part of the reason is cheap,. high-capacity mechanical HDs and the promise of SSDs. We just have this overabundance of storage options, and this disk technology is just one more drop in the ocean.

I often find myself looking at products and seeing a better model for a few dollars more, and saying "What the hey." Blu-ray needs to enter that What-the-hey area, where users will buy it instead of a standard DVD-R because it's not that much more money. And TDK's development, cool though it is, will have to be that way as well.

I agree, any improvements in optical media is going to sit in no-mans land until someone designs a reader/writer/player device that is priced at somewhere near reasonable for the average person.

While I would like to use this new disc, it will probably have a very high cost and the cost of me upgrading my DVD drive is also very high. Why bother when I can get a 1TB hdd for less than 8 cents per GB or if I really need optical storage a rewritable DVD is about 9~10 cents per GB (current blue ray discs cost at least 3x as much per GB and are not rewritable).

Until blue ray discs are 10~15 cents per GB, and blue ray writers are less than $80, I can't see there being any widespread adoption.

It will take time, and lots of it for them to decide that they want to sell quantity towards getting their profit. Any new tech is expensive at first but when The Sony 9 group of companies won the High-Definition wars I knew it meant high prices for a long time. We have all ended up on the The Sony 9 group of companies' teat this time.

They will not relent on licensing fees and allow the industry to relax prices until just before their patents expire.

During the BetaMax and VHS wars years ago, Sony lost that one and VHS became the accepted standard because it was much less expensive, though it was not "better".

Personally I've never had much luck with TDK media. I've found most of their stuff to be of pretty low quality.
