We’ve all gone thru the revolution of those optical discs. From those little 600MB on CD, then the DVD and now you’re probably in the midst of deciding between HD DVD and Blu-ray, for which is the best to store up your entire collection of porns. So, do you think those Blur-ray and HD-DVD optical discs that can store up to 50GB simply means a lot to you? No, it seems like we can get more here. A company called Mempile in Jerusalem seems to have found a breakthrough in the optical disc technology. What they’re talking about here is storing terabytes of data on single optical disc that have almost same dimensions with DVD. Their kind of disc boasts slightly thinker than a regular DVD but able to store up to 5TB of data, provided the blue laser is made.
So, what is the specialty about the Mempile discs that allows it to store up terabytes of data? As mentioned, the disc is slightly thicker than a regular DVD, which it consists of 200 of 5GB-layers to make up a terabyte of storage space. And these layers aren’t physically stacked, unlike any standard multilayer DVDs.
The Mempile discs is made of some special polymer that is known as ePMMA, which is also the reason that makes it carry a distinctive yellow color. And during the recording of data, the laser will “burn” only part of the plastic that is for state “1″ and leave those for state “0s” intact.
This approach is called the three dimension approach in the polymer, which is different from the two dimension used by regular DVD. The current technology still has limitation that allows write once and read many and the company is striving to make read/write drives available in the future.
Mempile has successfully produced couple of prototypes in the range of 600GB-800GB and the 1TB will be coming soon. And the 5TB blue-laser version is in its plan after that. According to the company spokesperson, that the disc has a life span of 50 years and the drives will likely hit the market in 2-3 years. Sounds promising? So, you could have a super optical disc to store up whatever you want, to cope up with the rapid increase in volumes of today’s media.

omg, thats a whole heck of a lot of data

Wouldn’t this cause some problems if it got a tiny scratch?

hi PooMan, I guess no this is talking about the internal structure, which shouldnt be affected by scratches on the surface

neahhh.. common.. it’s a disk.. they’re like becoming obsolete these days..

With 32 G USB flashdrives already available (almost?) how long before we have 100G or 1T in flash….then all disks will be obsolete.

This is like the 10th time since the turn of the millenium that someone has announced technology like this. None of them has ever managed to get a product on the market, though. Good luck MemPhile peeps, but I’m not going to get my hopes up til you actually get the thing on the market.

anthony,
U’re xactly rite. Solid state rulz.U can keep on creating high deenz disks
but everything depeenz on chipz

But we need he kind of not-so-easy erasable storage such as discs sometime. A flash just like hdd that you can delete your data by mistake. For optical discs with the current burner software, at least need you to go thru several “next” buttons and then confirm then only you can change the data in it. I still feel optical discs quite useful for more permanently storing data e.g for backup purpose

Ur deleting of your data disk mistakes has to do with you.The control over your data is especially important if you are an IT specialist and like any specialist you know better than to concentrate your info on any flexible media. Having said that,at least with solid state media you can better control who can deconstruct or remove data, thru devices like Trucrypt or other security software. Lazer discs have too many tunities
too to be destroyed physically either thur scratches or failure by dvd? players. I’m sure there will be comments against this idea. anything is possible.

Of coz, for the real IT people, we’re quite aware on how to protect our data. Being in IT, I’ve faced lots of novice users still pretty careless with their data, especially something on a flash drive or hard drive. So, optical disc could be a better choice for them. I guess the whole world is having more non-computer-literated users than the literated ones. Optical discs would be better choice for longer period of data backup

Letz just hope theeze copanies are wrking on a nu format totally T.
September 6th, 2007 at 7:41 pm
Yeah….
hopefully

Great discuss guyz T.

I thought that solid state storage is kind of volitile and should not be used to store stuff for long periods of time. Correct me if im wrong but arent you taking a risk by storing stuff on RAM which is what those drives are. I see a big problem with the new solid state storage drives being so big. Think of it like a bucket of water. The bigger the bucket the harder to carry and the more likely that you are to spill some water (data). The smaller the bucket the more careful you can be with it. I have been told several times by many security and IT professionals not to use thumb drives for long term storage, but rather a medium for transferance. With that being said I believe that optical drives should be developed more to fit the future needs of the companies to store massive amounts of data. Leave the thumb drives to the general public.

Cool….stuff my grandkids can use, stuff that I will not even remember or be around for to explain…storage of videos, pictures and the archival prospects of such a disc is essential.
Will this device become obsolete? Of course, remember those huge freakin’ floppy disks which were cutting edge? Quit being so negative people and look forward!

These discs can definitely come in handy!
