Pioneer Ultraviolet Laser Promises 500GB Discs
No Fortune writes "Here's an article indicating that Pioneer is developing an ultraviolet laser for data storage. Since the wavelength of ultraviolet lasers is shorter than the wavelength of blue lasers, the beams are finer and they can pack more data into per square inch. This gives a data rate 20 times more than the blue laser Blue-ray disk."
Microsoft Gamma Laser Promises 500 PB Discs
Here's an article indicating that Microsoft is developing a gamma laser for data storage. Since the wavelength of gamma lasers is shorter than the wavelength of ultraviolet lasers, the beams are finer and they can pack more data into per square inch. This gives a data rate 1,000,000 times more than the ultraviolet laser discs.
Looks like I have to buy the White Album again.
And there is nothing I want more than to wait 3.6 days for a disk to finish writing..
These should really come in some type of protective casing. Like a floppy or something.
I have many CD's and they were pretty resilient to scratches. They played fine even if they had a pretty hefty scratch on them.
Then I bought DVD's and I brought them on over sea flights for entertainment. I was transporting them in one of those CD wallets and they just started getting unusable really fast. The smallest scratch and it would stop working.
I'm thinking that these disks can get a scratch that is smaller than can be seen with the naked eye and it'll still be a real problem for the disk.
So they should either have a protective cover like a floppy or they should have lots of redundant information physically far away from each other on the disk.
The Internet is full. Go Away!!!
Someone already moderated you funny, but I think it's a real issue. Sure, use UV if it helps, but I would rather have them make the bits a little bigger and a lot more reliable than as small as they can get them and have them rot away. I could live with 100 gig of data on a disc if I could trust it a lot more than 500 gigs on one disc I can't trust.
I'm an American. I love this country and the freedoms that we used to have.
The limit is defined by the amount of power you can reasonably draw from your system to generate the radiation. Higher frequency means more power is required to generate a 'low-power' beam.
The other limit is finding a suitably reflective material that is cheap enough to be used as media. X rays pass easily through plastics, and they are absorbed by lead. Gamma rays pass through most kinds of material. You need something that reflects well, and doesn't absorb the radiation, that can also be used to store distinct states and be mass produced easily.
This is not a sig.
