120 DVD's on same size disc

[Jace]

Couple of excerpts:

"Japanese company Optware will commercialize an optical disc that can store more than 1 terabyte of data, and an associated disc player, later this year, the company said earlier this week.

The disc and player are based on a 5-inch optical disc like existing CDs and DVDs, but the new disc will be able to store about 120 DVD-format movies, according to Atsushi Machida, a spokesman for Optware.

The high capacity--around 20 times the storage available on existing discs--and a data transfer speed of 1 gigabit per second have been achieved by using digital volume holography read/write technology, developed under the Defense Advanced Research Project Agency (DARPA) in the United States, according to Optware's statement."



Terabyte Optical Disc in Development

I'll believe it when I see it. If it ever happens, expect to wait like 10 yrs for it to come down to cosumer lvl prices.

Ya, me too. But it would sure be nice. Remember HD-ROM promising up to 200GB on a translucent Cd-sized disc? Now you can't even find mention of that product on their website. Check Norsam

Sounds about right to me. I believe about 6 years ago I read in a government newspaper that work was being done on holographic storage. At the time they were talking about a gigabyte of storage in a 1/2 inch cube of holographic memory. I am pretty sure the test platform was referred to as packrat. They predicted that it would be commercially viable in about 10 years. This was not mearly an optical disk that was written to infrequently. This was a holographic cube that operating basically at the speed of light and could replace system memory. The research was mainly focusing on increasing the longevity of the material for read/write cycles and reducing the size of the equipment. The laser device to read the 1/2 inch cube was about the size of three 5 1/4 drives.

Me too. But thanks for the link tho, thats interesting stuff. I wonder what broadband speeds will be by the time its available commercially....maybe by that time one could download enough movies to fill one of these babies up and burn them on it all in one day!...

I think I remembered reading in the paper about a new media coming out called FMD that are extremely multi layered and will hold about 100gigs each. Suggested price was about $99 each. Don't know when they will become available but I couldn't imagine having a 100gigs on just 1 disc.

i swear companies make announcements like this just to attract investors, and then dwindle into nothingness..

whatever happened to multi-layerd fluorescent media???

that's what i thought.
