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."

Protective cover or lots of redundant information

[3770]

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.

Re:Bit Rot?

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.
