New Japanese research increases DVD capacity by 5000x

While we're waiting for the Blu-ray Disc Association to upgrade discs to 128GB capacity, Japanese scientists have found a way to increase DVD capacity by 1,000 times—using just a slick of metal material over each disc.

According to Shin-ichy Ohkoshi, the chemistry professor at the University of Tokyo leading the project, painting a variant of titanium oxide onto a DVD will conduct electricity when put under light, but when taken away from light it turns back into black metal.

Although it's unlikely to hit the market—at least, not anytime before the BDA launches those new discs—the Japanese team's claims of the DVDs holding 1,000 more data than a Blu-ray certainly are impressive.

Blu-rays hold about five times the data of DVDs currently (25GB per single-layered disc and 50GB for dual-layered discs, compared to 4.7GB for single-layered DVDs or 8.5GB for double-layered), and despite millions each year buying a Blu-ray player, plenty more still own DVD players and have no plans to upgrade.

EDIT: I bolded the things that point out that it's over 5000.

i heard about holographic discs which could store 500GB which is crazy in itself but to say 25000GB... is kinda unnecessary and strange unless they make HDD with tht tech

Won't these need a new player though if it is HD video on the discs?

This is true but its only the output that changes not the whole drive. For instance you could put it into a PC's DVD drive and read HD-Movies off it. Presumably anyway, it doesn't say if a laser or anything needs changed.

Now the Third Party´s doesn´t want program for it because has SO-MANY-SUPER-HYPER-SIZE!

nintendos already co-developing the holo-discs yes it's true.

sounds awesome...

This could certainly become interesting in the future. I like discs of multiple TB's

I might as well run my entire computer from a disc.

ykhan · May 25, 2010

some one got there b4 me with the over 9000 thing

25TB disks would rock.

I could care less to be honest. I hardly ever use discs anymore for my computer. I store everything on a slave drive and a USB storage device. The only time I ever use discs now is when I need to reinstall my OS and on rare occasions, backup my files if both of my hard drives and USB drive runs out of space.

Just when I think the age of physical media obsolescence is coming...

THIS happens.

Discs will be outdated very soon. I think flashmemory will take over the world, next to cloudnetworking.

Since when has there even been a 512GB USB flash drive? I'm pretty sure that 256GB flash drives were only introduced 4 months ago.

flash memory has got a long way to go yet to being the Isolinear chip
