Holographic Storage

I once heard about a storage device that would store information 3 dimensionally. Meaning that instead of storing it end to end, it would be able to stack end to end and on top of one another.

I think that it was a crystal type of device, no moving parts!

Has anyone else ever heard about this?

there is already a thread on this in trap17. they're stll developing it. shouldn't be finalised any time soon though. i heard they got their storage capacity to up 300GB per disk and plan on making them much much bigger. should be good when it becomes mass produced.

Intresting. Could somebody post the link to the other thread about this?

I feel compelled to pointout that DVDs also store data "three dimensionally".

Well "holograhpic" zould mean this has something to do with virtual images right, data can be send by viber optical cabels which would mean this could be possible, but sounds to be very hard to implent..

that would be insane... its like in all the movies where you see someone drop a diamond or a crystal into a computer, and it just reads the data off of it... i couldnt imagine that lol

Well it would be more like those cool 3d holograms that use to be on National Geographic. If you look at it one way you only se eit in 2d but tilt the image slightly and you see what's behind that object, hence the 3d. So data would be stored like that. I mean crystals themselves have thousands of areas of surface within the body of the crystal. Each surface being a place to store data dimensionally. Kind of insane, but super cool.

Sounds cvery expensive, I would rather stick with things like blu-ray discs, or use the same teqnique as UMD's but make the discs normal size, and use the whole disc without a hole, (if thyey can get a new way to spin the disc) coz the umds are like.. 1.7gbs and at the size of a normal disc, for home use they wood be great!

I like to stick with the old fasioned... but not too old fasioned.

I did a presentation at school some months ago about Holographic-Versatile-Discs (HDV). According to the HDV wikipedia article (http://en.wikipedia.org/wiki/Holographic_Versatile_Disc), HDV's have a capacity of 3.9 Terabytes (3900 Gb) and even much much more, counting with the double layer/side versions of HVD's. I can't confirm the veracity of this but there are other official sources from where you can get more precise information. HowStuffWorks also has information on HDV here.

By the way, while I was searching about the subject I also found an article named "Holographic Memory" (here) that could store terabytes of information

EDIT: Corrected some words ('HDV' to 'HVD', for Holographic Versatile Disc) Thanks Cerebral Stasis

Wow, That was the picture I was trying to find. Thanks so much for posting that Radioactive. Much appreciated.

Wait... Wouldn't a Holographic Versatile Disk be (HVD) instead of (HDV)?

In any case, it looks amazing! Thanks for sharing the information. Of course we will eventually reach a storage limit, but to see the current boundaries constantly being pushed is an exciting process.

It sounds really futuristic, almost ci-fi

I´d like to see it, it´s a strange concept. And yes, it also sounds rather expensive... but it´s all a question of time, I guess. In a decade we probably will be using this technology all the time.

Those disks can hold terabytes of data i guess.. So maybe it would make us bid farewell to our Cds and DVDs..

But i dont have any idea about the seek time it would have. If it has a good seek time, then maybe it would be one of the biggest product to get introduced.

We could make holographic ram chips, and who knows what they cood be used for, they may not be for pc's

Well, it would take awhile before they could be read-write, if ever, so they wouln't be used as hard drives for awhile.

And to that RAM comment, 64-bit processors allow for a few TB of ram, if I'm not mistaken. Problem is, we don't have RAM chips that big.

Thats alot of space lol, and if they are cheap (aka-100-300 dollars) which i doubt, but anyways think of all the hosting companys wood be able to offer, if someone cod say how much peeps trap17 has, if it is 3900 we could all have a gig each.... for a tiny lil disc, and if trap17 and other hosting companys had filled up a whole room with a server running on these discs, that wood be lotza space! They wood needa be ok to be in use for a long time, and computer running em wood needs lotza ram, maybe use 1 disc for ram, and but wow! thats alot of space, it wood take foreva to fill up one of those discs... u prolly need every mmocc in the world to fill it up... maybe more lol.

But how many users does trap17 have?
