Research team creates 150GB DVD-sized monster disc

Posted Jul 8, 2007 at 2:21PM EST by QJ Staff

Listed in: Tags: Berlin, gaming accessories, Microholas Project

The highest capacity we've heard of for current optical storage media is the Blu-Ray disc, whose double-layer format comes in at a monstrous 50GB capacity. That just might change in the next few years, as an ongoing research project has found a way to cram three times that capacity (150GB) into a DVD-sized disk, with plans to pump it up to a further 500GB by 2008.

The program, dubbed the Microholas Project, is under the supervision of the Institute of Optics and Optical Technologies at the Technical University of Berlin. The project team, under the direction of Dr. Susanna Orlic, managed to pull off this engineering feat by a process called microholographic recording, which they described as such on their home site:

On a microholographic disk the pit-land structure of a CD or DVD is replaced by microscopic volume gratings. These "microgratings" are holographically induced in the focal region of two counter propagating, highly focused laser beams: one beam is focused into the photosensitive layer and reflected back. The interference pattern of the incident and reflected beam results in a grating-like modulation of the refractive index of the storage medium.

In layman's terms, microholography recording creates three-dimensional holographic grids within the disk's nanostructure for storing and reading data. In comparison, traditional CD/DVD recording techniques use a two-dimensional pit-land structure that only uses the disc's surface for recording data.

Don't start turning in your HD-DVD/Blu-Ray players, though, as the Microholas Project's 150GB disk mentioned earlier is just a demonstrator of things to come. The team expects to have an even bigger 1 Terabyte disk out by 2010, with an expected read speed of 250 Mbits.

sure it can cram alot of memory. I think that they just coppied BlueRay and made it even better,.,. how come we didnt here about this before vlueray and Hd-DVD,.,.

and after all that,., just imagine the price. BlueRay is 5-15 bucks more than standard DVD so this new DVD will probably be $45, possibly even more,.,.

im sticking with Blueray

OMG! You're so stupid, I bet you need help taking a dump!

# blu-ray — Guest 2007-07-08 17:16

blu-ray is a dvd...

hd-dvd is a dvd...

all dvd means is Digital video disc.

That has nothing to do with resolution

# hmmmm... — Guest 2007-07-08 18:55

Uhhh,

Doesn't DVD stand for Digital Versatile Disc? Meaning it is capable of more than just video? Yes, I know, I'm right. It's okay. I don't gloat. Also, I think DVD can contain whatever resolution you want them to contain. The textures contribute to filesize and that was the real drawback of DVD. Larger capacity spawned higher resolutions. F.E.A.R on DVD held very high resolutions for PC, however, if you've ever burned a DVD movie you see how pixel size and quality correlate with file size.

# Yeah — Guest 2007-07-08 20:21

Yeah, I mean cmon, Bluray players are already in 5 million peoples homes, and by the time these come out im sure it will be 20 million. I don't think 20 million people willl suddenly go over to this new dvd disk and because it can hold more.

# digital versitile disc — Guest 2007-07-08 20:41

they are reffered to a both, and you made absolutly no sense down at the bottom... file size has nothing to do resolution, there are many factors

# ....... — Guest 2007-07-08 22:09

Uh yea the file size does matter, why do you think that they use blu ray and hd dvd for hd. cuz theres more memory storage and why do you think that hd videos on gametrailers are bigger than the standard videos.

# You wont see this long... — Guest 2007-07-08 23:40

What you people forget is the following:

1: This is just a technical post, not an actual product

2: Till you see this as a product to purchase, probably few years will pass

3: There's nothing said about production at all

4: Will it be reliable enought? Tiny scrateches on surface and you can trash the disk?

5: Is it really needed? Well, 1080p is the current max resolution for the standard called "FullHD". FullHD Movies perfectly fit on blue ray. So movies wont need the added space. Maybe for backup purpose this is nice, but not needed.

and so on...

# but... — Guest 2007-07-09 01:37

they have already created blu-ray discs that can hold up to 200GB.

# . — Guest 2007-07-09 04:43

i fink they can do 1080p but you cant fit a load of HD video on a dvd thats why they dont use it. i read that somwhere forgot where thou

# blu-ray — Guest 2007-07-09 05:29

the max amount of data a blu-ray can hold is 150gb because 25gb fit on one layer, 3 layer max right now on one side, dual-sided, do the math and a total of 150gb.

# only tecnological research — Guest 2007-07-09 06:16

***** men, is a university project, no a monster like sony, philips or thoshiba, those students maybe in the future work for this companies or found one.

this tecnologie is no founden in taking diferent lasers colors like HD-DVD or Blu-ray is microholographi c, the problem is take 50 layers to research 500 GB, to primitive by standars but still a prototipe.

Holographic tecnology is still in investigation in the Hard disck too

# ... — Guest 2007-07-09 07:38

Just call it a disc. Its not a DVD. Anyway I dont think it would be necessary until TVs start dishing out way more than 1080p, which wont happen for a awhile.

# gfdgdh — Guest 2007-07-09 10:06

incorrect rick.

8 layers are possible, prototypes have already been made. google it.

# No need to buy a blue ray and hd players anymore.... — Guest 2007-07-09 10:51

I've read in another article that it will run perfectly with your current dvd players so you dont have to spend $100's on blue ray or HD players.

# Doesn't anyone know about HVDs!?!? — Guest 2007-07-09 14:08

HVDs can hold a lot more then 150GB...

So far HVDs (Holographic Versatile Disc) can hold 300GB of information and in the future may hold up to 3.9 terabytes of data. (Thats a S**Tload of space!!!)

# just reaserch — Guest 2007-07-09 15:53

just imagine the price of each disk,.,

and this probably wont make it till the market till late 2008 at the least

# seriously — Guest 2007-07-10 00:05

i couldn't understand a thing you said because i couldn't read it you left out so many words that needed to be between some of your larger words

# 1 disk for all that porn — Guest 2007-07-10 00:09

only need 1 disk for all your porn no more haveing ppl find it on the computer=-)...jk

seriosly sounds great but what well use all that space? only for multiple movies and no single man made thing takes up that type of space no game well ever need over a trillibite of information however thinking about it if we ever do get holograms to work they may need these disks=-)

# bluray has over 200gb — Guest 2007-07-10 01:00

the max blu ray can have so far is just over 200gb with 9 layers they said it should come out within 2 yr

# Lotsa dumb ppl above me gosh! — na2rul 2007-07-10 02:27

Its Digital Versatie Disc, and its a brand name. Blu ray is NOT a DVD nor is HD-DVD. Bluray is bluray disc. Also the higher the resolution of a video, the more mbytes. therefore more space

# yep — Guest 2007-07-11 16:10

Yep I heard about HVD about a year 1/2 ago. Back then it would hold 1.6 terabite. (terabite+1000 gigs)

# DVDs can do HD — Guest 2007-08-04 14:18

When HD-DVD players first came out people were burning DVDs with HD videos and playing them on HD-DVD players, as all it comes down to is the codec support and resolution support. It's just that DVDs can't hold enough data for a whole movie in HD.

# regular players are not designed for HD video files — Guest 2007-08-04 14:29

Even if something crazy like that did happen, a normal dvd player or upscaler won't have the correct firmware and hardware to handle HD video on the discs themselves, let alone being able to read them. And with regular players, not even HD capable outputs.
