...Blu-Ray and HD-DVD claim they want to save us with capacities around 100GB, but even that amount looks puny compared to what Iomega recently received a patent for. It's called "Articulated Optical DVD," and if Iomega is to be believed, you could find 850GB AO-DVD discs in the near future.

The "articulated" part of the technology is mostly what allows for the great increase in storage density. Using nanostructures, which are microscopic grid-like structures embedded in the DVD surface, AO-DVD would allow recording using reflectivity, polarization, phase, and reflective orientation multiplexing to encode the data. Current optical technologies rely almost exclusively on reflectivity information alone, meaning AO-DVD would have a much higher information density. Iomega refers to this recording technology as "multilevel" since information is stored using multiple properties in a single physical space. The idea was so novel, Iomega won a Nanotech Briefs' Nano 50 award, a recognition given to "the best of the best" in the nanotechnology industry.

Iomega is currently studying the technology with an eye towards mass production. The company claims AO-DVD media and recording/playback devices could be constructed at costs similar to or lower than existing DVD's.
I don't think I would trust that much data on a single disc, but this is interesting all the same.

Also in the save vein: Holographic Versatile Disc.
Holographic Versatile Disc (HVD) is an advanced optical disc technology still in the research stage which would greatly increase storage over Blu-ray and HD-DVD optical disc systems. It employs a technique known as collinear holography, whereby two lasers, one red and one blue-green, are collimated in a single beam. The blue-green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc while the red laser is used to read servo information from a regular CD-style aluminium layer near the bottom. Servo information is used to monitor the position of the read head over the disc, similar to the head, track, and sector information on a conventional hard disk drive. On a CD or DVD this servo information is interspersed amongst the data. A dichroic mirror layer between the holographic data and the servo data reflects the blue-green laser while letting the red laser pass through. This prevents interference from refraction of the blue-green laser off the servo data pits and is an advance over past holographic storage media, which either experienced too much interference, or lacked the servo data entirely, making them incompatible with current CD and DVD drive technology [1] (http://www.optware.co.jp/english/what_040823.htm). These disks have the capacity to hold up to 3.9 terabytes (TB) of information, which is approximately eighty times the capacity of Blu-ray Disc. The HVD also has a transfer rate of 1 Gbit/s.

haha thats bigger than most people harddrives. you can have an entire hard drive on a disk, but if it gets scratched you're screwed. i suppose it's good back up though, better than having to buy a second hard drive, or having a ton of 800 MB Cds.


edit: 3.9 terrabytes? :eek: :eek: what the hell do you need 3.9 terrabytes for.

HOLY BALLS :D :D :D

...I have a little less than a TB in HD space, about 75% full and counting. I need to backup like a mothafucka, and that would melt my face off.

heh.. and here i was planning on putting a 200gb Network hard drive thinking it was big...

200GB is actually pretty small for network storage. I manage about 10TB of data on NAS and storage arrays here at work. Not to mention that 200GB drives have been out for about two years now, and 300, 400 and 500GB drives are pretty common now.

Wow...that's amazing. And the fact that they will cost about the same amount of money is revolutionary. This could be a huge step in the computer storage industry. I'll definitely get a few of these discs to backup stuff. That HVD is extremely impressive. I can't believe I've never heard of it. Good find! repped.

edit: You must spread some Reputation around before giving it to junglizm again.

maybe later, i guess.

yes but this is a small 2 computer home network and I was only planning on dumping mp3's, pictures, small videos, documents, and other hard to replace info..

Fair enough, but I still don't think 200GB is a lot of storage, even for a home PC/network...

yea jung, but think about it.

eventually they'll be able to replace old HDD plates with mounted HVD's. Those 3 tb of servers that you manage will be compacted into a couple drives! This is exactly what the computer economy needs in preparation for bigger files: more readily available storage space. thats why i said "this is revolutionary".

I'll take a dozen... :D

As to how many I'd need to backup my systems ... Mass Storage: 250+250+160+120 Systems:148+120+40+40. I wouldn't trust that much data on a single disc, so I'd burn multiple copies. Would probably be wise to have some sort of recovery built into this storage, similar to PAR2.

I'm gonna miss the days when you could use a CD as a frisbee, pop-it into your CD player/Computer/Playstation/Sega Saturn and say "Hey! It still works!"

If these formats take 30 seconds to change tracks I'll laugh so hard.

Still, cool, nonetheless. With 3.9TB of data, I could backup my massive porno collection on two discs! Yeah, you all wish you had enough stuff to fap off to as me.

On a side note, I had the most disturbing night of my life last night and didn't sleep well.

there goes my thinking my 40 gig HD is big.

ps. If anyone has a HD to share, I'd greatly appreate it. I have about 2 gigs until this one is full. :(
