DVDs Could Hold 1,000x Capacity of Blu-rays With New Japanese Research
By Kat Hannaford, May 24, 2010 10:03 AM

" 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.

What a coincidence. Just as everyone has finally bought a Blu-Ray player, they start development on a new format.

How many times does the article need to say "DVD" for you to realize they're talking about modifying an old format?

Even if it was a new format, don't pretend like this is some sort of conspiracy. Welcome to technology.

good thing i haven't.

Will the discs be readable on a standard dvd player?

Will these discs have to be manufactured or can you burn your own?

Calling it dvd after adding new materials is a bit misleading.

But we have seen no proof yet.

If this "slick of metal material" works on a DVD, shouldn't the same be true for Blu-ray? The only difference (that i know of) between DVD and Blu-ray is the actual laser beam Blu-ray uses, which can read/write data a lot smaller than a regular DVD laser. So if a dvd can hold 1000x the capacity of Blu-ray with this new technology, shouldn't Blu-ray be able to hold shit-loads more?

I'll believe it when i have 1 burning, And the cost?

[BlueMax]

as long as movies don't need a format or media that require "1000x capacity of BD", I don't think this innovation will have any commercial success.

The Redbook CD is already obsolete and more and more people are downloading music to their iPods or some better media player.
Audiophiles are beginning to discover that storing files in a lossless format on an HD and streaming it, is far superior to the jitter ridden method of retrieving bits from an optical drive.

The notion of stroring data will soon be out of date.
With the ever increasing speed of the BB and beyond, consumers can play on demand, from huge databases of HD movies, bit perfect audio and w.h.y.

I wonder what the costs will be, and what use do we have for a disc with that much capacity? As long as they are going for the 1080p standard, they will not need it. Anyway if would probably cost shitloads to get that comercialized enough for it to become regular.
