200GB's on a single optical disc.

I saw this story at this page dated September 3rd, 2003:

"Novel optical disc stores 200 Gb of data

Samsung Electronics of Korea and Japan?s National Institute of Advanced Industrial Science and Technology (AIST) have developed a new optical disc technology capable of storing 200 Gb of data on a disc, compared with 23 Gb for the emerging Blu-Ray Disc system.

The technology uses a violet laser diode to write data onto a spinning disc made from a special resin film on a glass substrate. The resin expands when heated by the laser, creating a 50 nm bump that functions as the data bit.

Samsung is one of a number of companies in the Blu-Ray Disc consortium, while Toshiba and NEC are developing a rival standard, Advanced Optical Disc (AOD). "

Things are going to get very confusing when all these standards start coming out. Is 1 terabyte of data on a single, DVD compatible disc which sells for 10cents a disc so much to ask for? 😉
 
Seeing as how Samsung and Toshiba have merged their optical disc operations into one huge company, I doubt they'll be release two competing standards from one company.
 
Wow, that is a ton of storage!

I would assume that this would be extremely expensive and won't work with current hardware. It would be a few years of waiting I would say

Lossless high resoultion video.

The ultimate standard.

Until someone can fit a whole movie in 1990X1440 lossless, (Which would take about 350GB, if I remember right) then the industry will always need more storage. I'd like to see HDTV standard MPEG-2 compression on a disc, soon. In decent compression ratios, too. No less than atleast 8 megabits per 720X440.
 
mnmm .. transferring 200 GB from an optical disc to hdd is really fast. I think companies need to come up with something that uses ATA150 to the fullest.
 
MMmmmmm.... DVD2. 😛

Even DVD was uuber-expensive when it was brand new. But what ever happened to crystalline solid-state storage, eh? 🙂
 
Two problems with that. FIrst of all, can't be massed produced with information on them. There's no 'Stamping' like procedure like you have with DVDs.

2nd of all, you *cannot* expose these guys to light. Once you do, it's like what happens to photographic film. *POOF!*.

So the storage requirements are very stringent, and it makes it unsuitable for anything but backup.

Last time I heard there was a version of this drive, a disk about the size of a floppy disk was used for storage, write only. Could store about 100 gigabytes. Insane read/write speeds compared with DVDish mediums. Nearing 7200RPM harddrive level.
 
One problem.

NO one has figured out how to make rewritable holographic media, so far. Or atleast, at the production stage.

If you want a write once harddrive, then the above mentioned product would probably fit your bill. But rewritability is a completly different matter.

That's why you can't expose it to light before you write it. (After is fine.). Because it's irreversable. I bet rewritability isn't impossible, though.
 
Expensive, write-once, high-capacity ZIP disks... well.... new technology could mean improvements somewhere else at least.

by the time such a media exists, processing speeds/performance will be phenomenal enough to where you could probably store the same video with 70gb. but why would you want it lossless. for most things, a good compression algorithm is good enough. most people use mp3's for music and jpg for pictures (digicam pictures), and so would prefer to store more, than store more accurately
 
Simple.

During editing, errors can build up. If you have lossless, you never have to worry about the new content changing the situation of the scene (Thus, during recompression, changing the scene itself).

Besides, why do people choose CD over Mp3? Because they like the way CDs sound. Espically on a Hi-Fi system. I'm sure if everyone *could* go lossless, they would.

If you could get lossless 720p, wouldn't you? Even if it cost you a few extra $$$?

Thats incredibly short sighted, though I'm sure people thought the same thing when CDRW and DVDRW were being developed. Good thing people think differently, or we'd all still be rewinding VHS tapes and swapping out 10 floppies to play Kings Quest XXIIXX😀
 
the whole not-exposed-to-light thing can be easily solved - an outer container that opens inside the sealed reader. like floppy discs, except you wouldn't be able to open it all too easily.

we'd need some mad read speeds on this thing to be able to play the lossless video without stutter, though.

Exactly. I swear to God, do you people ever learn? How long has this been going on? When the HUGE 2GB hard drives came out, people didn't know what to do with ALL that space. Same with 300GB drives now. How could anyone use up a WHOLE 300GB drive? It is easy, you just have to put your mind to it. 😉 I could actually use a few terabytes worth of space, but then I'll need 200GB+ optical discs to back it up now wouldn't I. I swear, some people have no vision what so ever.

I don't remember the word at the moment, but i'm the kind of person that, if you give me a 60 gb hd, I'll be able to use the computer with 1gb of space free comfortably... If you give me a 200gb hd, i'll be able to use the computer with 1gb free comfortably ^^

Yeah me too, but I get my "neat-freak" moments and delete stuff I don't use like crazy. I don't know why 🙂 because it's not exactly costing me anything lol.
