"5 dimensional" 1.6 terrbyte disks the size of DVDs

A new optical recording method could pave the way for data discs with 300 times the storage capacity of standard DVDs, Nature journal reports.

The researchers say this could see a whopping 1.6 terabytes of information fit on a DVD-sized disc.

They describe their method as "five-dimensional" optical recording and say it could be commercialised.

The technique employs nanometre-scale particles of gold as a recording medium.




Sound pretty strange to me, but it also sounds promising. (nana2)

It's called Holodisc, and each "dimension" is supposed to hold 320GB of data. There is supposed to be a limited release later this year that only uses 1 "dimension" (I'll call them layers from now on), and thus, will be 320GB.

The hope from some is that Blu-Ray will fail due to the economy and DVD, among other factors. Holodisc (or HD) can support playback of 1080p in an uncompressed format (this would be 1.15TB per 90min movie). Lack of compression means that less processing power is required for video playback, as decompressing in realtime takes a lot of CPU power (hence why BR players are so damn expensive). So in theory, the main hardware for an HD player would cost less than that of a BR player. However, the lens and media itself would cost more.

If Blu-Ray succeeds, it's doubtful that HD would even try to enter the movie market though. Consumers do not want another format war so soon after the last one.

No, this is nothing like Holodisc technology, this is much simpler.

Heh, that's not even possible today. That's over 1GB per second of data. Most RAID arrays can't handle that much data let alone a 4x PCI-E bus. (1GB theoretical)

Let's say 100MBps. (Velociraptor transfer rates) 1 minute = 6GB. 540GB for a 90 minute recording. That could fit on a "2d" holographic disc. That is still pretty unlikely that a disc could even be read that fast. 8x Blu-ray is 36MBps.

Uncompressed video isnt really needed though, you can have a simple lossless compression algorithm that takes less processing, but also takes up less room then uncompressed video.
And thus should actually work within limited bandwidths of any storage media.

Though honestly, I dont like the idea of 2 hours of video taking up over 1TB, it will eventually happen, but only after we have moved higher then 1080p

Indeed, compression is almost always preferable to an uncompressed data.
Especially when we have data which compresses so incredibly well without perceivable loss in quality.

1080p is decent amount of resolution what would be nice for the next step is stereo image with temporal resolution of 60 FPS or more.
This would be must for movies with fast action in complex scenes IE. Transformers, which really lost quite much because of the 24fps of the film.

I dont think this will be used for video, although it rumoured that extreem hd (7680 * 4320) is a future home cinema technology. Thats somewhere between cinema and imax resolution.


In truth i see this technology being used for games and large programmes.

or on final fantasy game cutscenes -.-

Lol, they do love their cutscenes, I do too though, I wouldnt if the CG wasnt as good as it is though(Just like Blizzard, though Blizzards are way better).

I never thought about stereo imaging, and higher FPS, the main reason 24FPS has been fine is because of motion blur, but I wouldnt mind a higher FPS since the tech has been capable of it for awhile now(though that will take higher processing power), thats definently a viable way I can see the filesizes jumping up alot

It will eventually, but currently I dont see the need for optical media that large for games, even Vanguard which was a massive game when installed of like 16GB or so, is able to fit on a DVD once packaged in an install, bluray is already on the market, its the only format allowing at least 25GB on a single layered bluray, which even in its installed form Vanguard wont fill up the whole disc, plus all they need to do is have 2 layer bluray and they will be able to fit any game on it for probably the next 10 years, at which point larger optical media starts becoming viable.

Until then though, I predict this will mostly cater to backups for various companies, in datacenters in the likes.
I could also picture it in use for security camera footage, allowing more video per disc.
But until the games/movies catch up, it wont work currently, and will be too expensive for the general public(I am sure some people are still using CDs prolly because they are 50cents cheaper then DVDs, or they simply havent bothered upgrading their ancient crapbox with a dvd burner)
