New Technique For Optical Storage Claims 1 Petabyte On a Single DVD

samzenpus posted about 10 months ago | from the that's-a-long-movie dept.

Data Storage 182

melios writes "Using a two-light-beam method a company claims to have overcome Abbe's Law to dramatically increase the storage density for optical media, to the 9 nm scale. From the article: 'The technique is also cost-effective and portable, as only conventional optical and laser elements are used, and allows for the development of optical data storage with long life and low energy consumption, which could be an ideal platform for a Big Data centre.'"

That's what batch jobs are for. Computers can do more than one thing at a time, even with a storage medium. That's how Tivos can do the voodoo that they do.

Just set it off an wait until it's done.

Same as cloning a 10TB disk array (which I already do now).

Optical density, schmoptical schmensity! (5, Insightful)

OliWarner (1529079) | about 10 months ago | (#44068605)

Supersnore. It's another year and another story about 1000-sublayer thick DVDs using multispectral lasers to fit ALL the DVDs on it. But how many of those make it to market? How robust is it? How much does that media cost?

I've been reading stories like this for 20 years and I still get little-girl-meets-Bieber excited when I think about being able to back up to just one disk... But it never happens. Spinning rust remains the cheapest and most convenient mass-storage device.

Crookdotter (1297179) | about 10 months ago | (#44068613)

If I've RTFA correctly, this is one layer. they are circumventing Abbe's law by superimposing 2 beams where an effective write only occurs at the overlap, allowing a writing beam of 9nm.

Re:Optical density, schmoptical schmensity! (4, Informative)

jkflying (2190798) | about 10 months ago | (#44068667)

Almost. The overlap causes destructive interference, so the only place where the write occurs is in the centre where there *isn't* overlap. But yeah, this is single layer.

Re:Optical density, schmoptical schmensity! (4, Informative)

Pinky's Brain (1158667) | about 10 months ago | (#44068977)

A single diffractive optical element could achieve both those functions, but those can't get below the diffraction limit either in the general case (superoscillations can do it as a special case, but those don't really produce spots).

What they are actually using is two photon absorption, the two beam setup allows them to have a tighter distribution of two photon absorption events.

Not sure hard disks are the cheapest ones. On Amazon you can buy a 100 dvd-pack spindle for less than 25$, and that'a almost 500 GB.

Re:Optical density, schmoptical schmensity! (0)

$25/500GB = $0.05/GB

Alternatively you can get a 4TB drive for $200. $200/4000GB = $0.05

So for the same price per GB do you want 100 discs or 1?

Some 100-dvd boxes are even less than 20$ if you search, but yes, one single huge hard disk is better in many cases (not in all cases anyway). With blue-rays boxes the ratio is even better. I was just pointing the fact that hard disks are not yet the cheaper per gigabyte.

at an OPTIMISITC writing speed of 1GB/sec (5, Insightful)

etash (1907284) | about 10 months ago | (#44068629)

it will take about 1million seconds to fill it or about 11.5 days

Re:at an OPTIMISITC writing speed of 1GB/sec (5, Insightful)

TheRaven64 (641858) | about 10 months ago | (#44068717)

If I had an optical disk that had that kind of write speed and sufficiently cheap media, I'd use it with a log-structured filesystem. The real data would be on some other media, and the optical disk would record every transaction. When the disk filled up, I'd pop a new one in, have it write a complete snapshot (about 40 minutes for a 2TB NAS, and I could probably buffer any changes in that period to disk / flash) and then go back to log mode. Each disk would then be a backup that would be able to restore my filesystem to any point in the period. Actually, given my average disk writes, one of these disks would store everything I write to disk for about 200 years, so it would probably want more regular snapshots or the restore time of playing back the entire journal would be too long. Effectively, the append-only storage system becomes your authoritative data store and the hard disks and flash just become caches for better random access.

The problem, of course, is the 'sufficiently cheap media' part. When CDs were introduced, I had a 40MB hard drive and the 650MB hard disk was enough for every conceivable backup. When CD-Rs were cheap, I had a 5GB hard drive and a CD was just about big enough for my home directory, if I trimmed it a bit. When DVDs were introduced, I had a 20GB hard drive and a 4.5GB layer was just about enough for my home directory. When DVD-Rs were cheap, I had an 80GB hard drive in my laptop, and 4.5GB was nowhere near enough. Now, the 25GB on an affordable BD-R is under 10% of my laptop's flash and laughable compared to the 4TB in my NAS.

If they can get it to market when personal storage is still in the tens of TBs range, then it's interesting.

My first floppy drive on my C64, disks cost me 2 bucks each, it was 2 buck when I got a 3.5 inch drive, it was 2 bucks a blank when I got my CD burner the first time, it was just under 2 bux a disk when I got my DVD burner and I will wait and see what the price for blanks when they sell this drive, if they ever do that is.

pwizard2 (920421) | about 10 months ago | (#44069923)

I remember using packet-formatted CD-RWs as one form of backup in the late 90's-early 2000's, your post reminded me of that. The problem is the discs would go bad without warning--I could still read from a bad disc with no problems but any new writes would fail and the disc would be ruined after that. Optical media is too damn unstable for backup purposes even if hard drives were still small enough for it to be practical.

The only way to do backup is rsyncing between several external discs on a regular basis and storing at least one off-site.

Re:at an OPTIMISITC writing speed of 1GB/sec (1)

Anonymous Coward | about 10 months ago | (#44068745)

Re:at an OPTIMISITC writing speed of 1GB/sec (0)

Don't write it all at once. There are many situations where this is sub-optimal but that doesn't means that there aren't situations where it is useful.

Say that you want to do nightly backups of your project folder. This could be a convenient way to manage that. Changing DVD every now and then isn't that problematic.

Have 2 laser heads. Or 4. Or 8. or X many as you can fit inside the housing. I thought there was a CD-RW (or maybe DVD-RW) drive that already did something like this with 3 laser heads.

Or combine the above with the disc precisely balanced and mounted in a case similar to a hard drive so that the disc can be spun faster than a conventional optical disc. You lose the portability, but you're still far ahead of magnetic storage density.

There are ways to 'double up' mask steps into one reticule to save money on medium volume ICs and small volume has to be done on MultiProjectWafers.
Direct write is slow but with a multiple beam setup that can be speeded up. I'm thinking what Mapper Technology is trying to do with e-beam.

Optical media sucks... (4, Insightful)

RedBear (207369) | about 10 months ago | (#44068905)

I've just about had it with all optical media in general. I've had numerous CDs and DVDs over the years that just stopped being readable without even having any visible damage. Both self-written and factory discs. I'm only halfway through re-watching a retail set of Stargate SG-1 DVDs I purchased at Costco for $179.99 just 3-4 years ago, and I've already encountered a handful of discs with serious defects. Learned my lesson not to buy physical media anymore. Once I finish torrenting a good pirated version of the series I'll probably never try to watch the DVDs again. The box is nice though.

Bottom line is even if one of these amazingly high density optical media schemes finally pans out, the media will need to be composed of pure diamond or something else incredibly durable, and have a filesystem with incredible levels of error correction and redundancy or it will be pointless to put even a terabyte of data on such a disc, much less a petabyte. And that's not even bringing up read/write speeds and other issues that have already made this type of media useless for many purposes.

Re:Optical media sucks... (4, Informative)

Pinky's Brain (1158667) | about 10 months ago | (#44069001)

It's not deterioration of the plastic which causes CDs/DVDs to be unreliable, it's de-lamination of the reflective layer and deterioration of the organic dye for the recordable ones. The first is just causes by poor manufacturing, the second is a little more serious but the method in this article doesn't use dyes, it uses photopolymerization ... which would not necessarily be as failure prone.

Optical media is use-once, maybe twice if you're cautious.

If you're having discs you burned go tits up on you when stored in a cool, dark place, then you should probably start researching the media a little more carefully. Or just buy whatever Verbatim wants the most money for. They made some of the best floppies, and guess what? They make the best optical media.

swb (14022) | about 10 months ago | (#44069897)

My first DVD player was an Apex, back when it was a big deal to reflash it with region-free/no macrovision firmware (circa 2000?). At some point I ran into issues with this player when MPEG2 bitrates went over some threshold (5 Mbps?) -- the player just didn't have the horsepower to handle that data rate.

Eventually that player died and I went through a series of inexpensive Chinese players. Some failed outright after six months, but those that didn't die would often choke on some discs, freezing in the middle of playback or stuttering every 15 minutes.

I finally gave up and spent nearly $100 on a name-brand player and all those problems went away....until I got into Bluray players!

I bought two nearly identical Panasonic Blu-Ray players, hoping that a big name and higher price bought me better equipment, but these players have also been flaky, although not as bad as the Chinese DVD players, requiring full power cycling (pulling the plug) from time to time.

Usually the content (seems most common with HBO discs) freezes and won't continue, like it has a tracking error. Sometimes you can chapter skip and it will continue playing, but usually I pull the plug. Some software updates have helped, but it still happens too often. A Sony purchased in the last six months doesn't do this.

Anyway, the moral of the story is test your discs in better players. I kept home-burned CD-Rs in my car for years and was terribly abusive to them (left on the seat, jammed 3 into one slot in the visor holder, etc) without ever having problems except for the most obviously scratched discs. Other than some very early Kodak CD-Rs I burned in the late 90s optical media, whether factory or burned hasn't been an issue as much as the player hardware has.

Don't get excited until it ships (4, Insightful)

Those clowns at InPhase ("Holographic Discs") were like the Duke Nukem Forever of storage; well over a decade, and no shipping product.

For now, I put this in the same pile as the Windows Database File System and Laptop Fuel Cells.

How many NSA data centres can be fitted onto a single optical disk?

[...]
Approximately 600 million times per second, particles collide within the Large Hadron Collider (LHC). Each collision generates particles that often decay in complex ways into even more particles. Electronic circuits record the passage of each particle through a detector as a series of electronic signals, and send the data to the CERN Data Centre (DC) for digital reconstruction. The digitized summary is recorded as a "collision event". Physicists must sift through the 15 petabytes or so of data produced annually to determine if the collisions have thrown up any interesting physics.

Optical density. (1)

MachineShedFred (621896) | about 10 months ago | (#44068987)

Yay, an optical disk with 1000x the density of DVD! That means that when it gets scratched, you'll lose 1000x the information that you would on a DVD!

Let's all sing along now: Tape sucks, Optical sucks. Rotational drives are here to stay.

if physical contact with the media is so dangerous, have these disks mounted inside a traditional enclosure, like an old floppy disk.
Preventing accidental contact with surfaces scratching is a well solved problem ...

Agreed. Also with such a high density, they could be a smaller physical format and double sided, like those Sony music discs back in the day.

Which means they won't work in a standard drive - kind of kills the reason for putting it on a DVD in the first place.

Well, its is fairly obvious that you could create a data format that uses this as an advantage. Reduce the total data capacity in return for 1000 backups on the same media if one is corrupt just go to the next one. That is the major problem with current media... there isn't enough redundancy. Then all you have to do is wait for it to seek though 999 corrupted versions to get to the good one! I was always a fan of MiniDisc mainly because of the floppy style case to keep even a poorly guarded disk relativly pristine.

Depends on the cost. If these discs are under $20, I can back up my home storage array with substantial FEC for 10% of the cost of the array. Twenty times even before breakeven.

Backup media (1)

kelemvor4 (1980226) | about 10 months ago | (#44069277)

Wow, it's been YEARS since there's been any kind of usable backup media solution. 1PB seems like a good starting point, IF the speeds are reasonable (i.e. able to write 1pb in a few hours). Even most home users have at LEAST a TB these days. Datacenters?

So by DVD you mean.. (0)

Anonymous Coward | about 10 months ago | (#44069909)

You mean this method inccreases the amout of data that can be stored on a 12cm optical disc, right?
This method won't increase the stroage of a DVD disc.
