DVDs Could Hold 1,000x Capacity of Blu-rays With New Japanese Research


Recommended Posts

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 timesusing 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 marketat least, not anytime before the BDA launches those new discsthe 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.

1000 times the DVD capacity!!!! 4.7 TB in a DVD!!! those guys in japan must be joking!!!! If its true its amazing!!!!

and i dont see this coming to DVD soon since it is still in research.

That is pretty impressive, however what is stopping this type of technology from entering into any type of optical storage medium? I'd assume the same manufacturing process could be replicated to meet BD specifications and add greater storage capabilities to BD as well.It's always great to see these research projects and find out what is being engineered out there.

Any word though on if current DVD players could even play these discs? I'll stick with Blu-ray :)

Probably not it would at the very least require a firmware update or more likely new hardware so the title is a bit misleading.

DVDs Could Hold 1,000x Capacity of Blu-rays With New Japanese Research

25GB * 1000 = 25000GB = 25TB ;p

25GB * 1000 = 25000GB = 25TB ;p

yeah saw that too but read the first line on the article. "Japanese scientists have found a way to increase DVD capacity by 1,000 times"

The title says 1000x bluray but the article says 1000x dvd. I think the whole thing is a joke.

I suspect it's a bit of an overestimate anyway I think we're more likely looking at several 100 GB maybe 1TB, 4.7 seems a bit wild. but i'd love to see it if they can.

Japanese scientists have found a way to increase DVD capacity by 1,000 times

does that mean they've actually done it or just found a way to do it....cause there's a bit difference

Why are they calling this a DVD? It is no more a DVD than a CD or Blu-Ray disc is.

Probably because its using the same basic technology platform as a DVD just with a layer added, Blu-Ray and CD use different materials and technology.

painting a variant of titanium oxide onto a DVD

Boring.

Let's face it, we're not going to have a useable version of this any time soon. Just as 3D will never take off as many people have just bought a new HD TV, so they're not going to go out and buy another so soon.

Technology needs to slow down, or more research needs to be done into things like this so instead of 3TB HDDs creeping onto the market, we have drives that are 50TB as let's face it, it's going to happen anyway!

I agree. I really do tire of this marginal improvements trying to flood the market. Some things are better done in well crafted leaps.

This would be the ULTIMATE backup system, you could put all your media on it, then just keep it in a disc cover and keep it safe.. perfectly and doesn't take up much space. But I would happily bet you guys a few bucks that it will cost alot more then it it potentially could, because of the high storage amount vs. current prices.

They should start researching how to make these things faster too, because a disc that holds a few TB will certainly be a pain to use with current speeds...

it would be faster due to much higher data density

Not excited because we already have 2948323403258234502340-TB blu-rays. It's called streaming and in my view they're the future down the line, as broadband becomes wider spread and more options become available, which believe me, it's coming. I think it'll outgrow physical media in the next decade.

^ Perhaps so, but I would like to keep all my data safe with me, not with some 3rd party company somewhere accross the world thank you.

You scratch it, it breaks. It gets too much humidity, it breaks. You're on the road and you left it at home, you can't watch it. I understand that sense of safety the cloud will somehow take away from us, but in the end the data will be managed professionally and backed up multiple times a day to insure its safety. In the end...

Not everything can be streamed though and as a portable medium it is nice. Not to mention that all data on any medium could be destroyed. You can't view your content without an internet connection with streaming so if the network goes down or one is unavailable your data is stranded.

What they really ought to do is to up the capacity but make the disc size smaller so it can fit in more devices and be easier to carry around. They should also design them like mini-discs/floppies so that the disc is in a protective case all the time.

A 1TB (or higher) disc the size of a mini-disc would be cool.

    • AMD RX 9070 GRE AI, Blender benchmarks vs 9070 XT, 7800XT, Nvidia RTX 5070, 4070 by Sayan Sen Earlier this week, we shared the first part of our review of AMD's new RX 9070 GRE. It was about the gaming performance of the GPU, and we gave it an 8 out of 10. As a follow-up, similar to how we did with the 9070 XT and non-XT, we are doing a dedicated productivity review for the RX 9070 GRE as well, where we compare it against the 9070 XT, 9070, 7800 XT, as well as Nvidia's 5070 and 4070. This will include AI, rendering, compute, and more benchmarks. AI performance, especially, is a very important metric in today's world, and AMD also promised big improvements thanks to its underlying architectural improvements. We will be pitching it against the data we already have for the RX 9070, and RX 9070 XT, but also the Nvidia 5070 FE, MSI GeForce RTX 4070 VENTUS 2X 12G, and Gigabyte Radeon RX 7800 XT GAMING OC 16G as they are in a similar price class, but also because we do not have a comparable 5060 Ti card lying around here that we can compare it against. Before we get underway, this is a collaboration between Sayan Sen and Steven Parker, who lent me his test bed. Also, there was no editorial input from AMD. First up, the specs of the RX 9070, 9070 XT, and 9070 GRE, which were given to us by AMD: Radeon RX 9070 GRE Radeon RX 9070 Radeon RX 9070 XT Boost Clock: Game Clock: up to 2.79GHz up to 2.20GHz up to 2.52GHz up to 2.07GHz up to 2.97GHz up to 2.40GHz Stream Processors 3,072 (48 CU) 3,584 (56 CU) 4,096 (64 CU) Ray Accelerator 48 56 64 AI Accelerator 96 112 128 ROPs 96 128 Texture Mapping Units 192 224 256 Memory 12 GB GDDR6, 18Gbps Clock, 192-bit Bus 432 GB/s 16 GB GDDR6, 20Gbps Clock, 256-bit Bus Effective Memory Bandwidth: 640 GB/s Infinity Cache 48 MB (3rd Gen) 64 MB (3rd Gen) Card Bus PCI-E 5.0 X16 Output 2x HDMI 2.1b 2x DisplayPort 2.1a Power consumption 220W 304W Recommended PSU 650W 750W Slot width 2x 3x Price (SEP) $549 $599 As you can see from the specs above, it is less than the standard RX 9070 in every way that counts, except for slightly higher Boost and Game clock speed. Design Moving on, the RX 9070 GRE we were given is an XFX Swift triple-fan, dual-slot design with two 8-pin connectors. At 30cm (self-measured), it will fit in most systems easily. There is no RGB either. The AMD Radeon RX 9070 GRE by XFX from all angles. Test system Our test system consists of the following: Lian Li O11 Dynamic Mini V2 Flow (Amazon|Newegg) ASUS Z890 ProArt Creator WiFi (Amazon|Newegg) Intel Core Ultra 7 270K Plus (Amazon|Newegg) Thermal Grizzly KryoSheet - 44x37 (Amazon|Newegg) 2x 16GB G.Skill Trident Z5 RGB (7200 MT/s in XMP) (Amazon|Newegg) Sabrent Rocket4 Plus 2TB SSD (Amazon) Windows 11 25H2 (Build 26200.8246) AMD shared a press driver based on the recently released Adrenaline 26.5.2 that we were required to use. We now move on to our benchmarks. First up, we have Geekbench AI running on ONNX. For some reason, the 9070 GRE does exceptionally well here in both half-precision (FP16) and single-precision (FP32). It manages to beat the RTX 5070 and RX 9070 non-XT, and is only behind the 9070 XT. Since Geekbench runs in short bursts instead of continuously hammering the graphics card, it seems the GRE's faster boost clocks are helping here. Next up, we move to the UL Procyon AI test suite, starting with the image generation benchmark. We chose the Stable Diffusion XL FP16 test since it is the most intense workload available on Procyon. The Nvidia cards do very well here, as even the 4070 out-muscles AMD's best fairy easily. The positive thing about the GRE is that it gets quite close to the 9070 non-XT in this test; this indicates that the VRAM does not play a very big role here, as SD XL relies on float16 (FP16). So this is something to keep in mind again. If you wish to work with float32 AI workloads, graphics cards with larger than 12 GB buffers would likely emerge as victors. Regardless, the gains are still massive on AMD's 9000 series compared to the 7000 series. Following image generation, we move to the text generation benchmark. This is one test where the 9070 GRE struggled, quite a lot. It seems that the 12 GB VRAM and lower memory bandwidth of the new Radeon 9070 GRE are hurting it quite a bit; the split is massive, especially in a test like Llama2, which packs 13 billion parameters. As such, in all the tests, the 9070 GRE is the slowest of the lot. Next, we tried Blender, and here the AMD GPUs were beaten by Nvidia. Rendering is something the Green team has always had a lead over the Red side, and it has not changed so far. On the positive side, though, the 9070 GRE shows significantly better results than the 7800 XT, which means AMD is on the right path. Catching up to Nvidia, though, will require a lot more effort. And we hope HIP and ROCm can keep improving. Wrapping up AI testing, we measured OpenCL throughput in the Geekbench compute benchmark. The RX 9070 GRE alongside the 9070 did not fare well here at all, even falling behind the 7800 XT. Interestingly, even the RTX 5070 could not beat the 4070 on OpenCL, so perhaps this suggests that OpenCL optimization may not have been a priority for either AMD or Nvidia in the modern era. Conclusion We reached the end of our productivity performance review of the 9070 GRE, and we have to say it's a mixed bag. Unlike the 9070 and 9070 XT, the GRE excels in some areas while losing ground fairly easily in others. Similar to how it happened in gaming, any time the card's memory subsystem gets hammered, it tends to fall behind the others. This was the case with text generation, wherein we saw the VRAM sometimes hit its maximum available 12 GB of usage with larger model sizes. So what do we make of the RX 9070 as a productivity hardware? It can certainly be used, but you have to know it has its limitations. For those looking for a GPU that can deal with more, AMD recently unveiled the Radeon AI PRO R9700, which is essentially a 32 GB refresh of the 9070 XT with some additional workstation-based optimizations. On a similar note, the new Ryzen AI Halo platform is something you can consider if you want to set up a local AI processing station. Considering everything, we rate AMD's Radeon RX 9070 GRE a 7.5 out of 10 for its productivity performance. Price is less of a factor for those looking at productivity cases compared to those considering the GPU for gaming, and as such, we felt it did quite decently on many occasions and can be handy if you need a 12 GB GPU and, for some reason, don't want to get Nvidia.
