Pioneer Ultraviolet Laser Promises 500GB Disks

10 Nov, 2004 at 11:50pm ET Article published in Tech

Japanese hardware maker Pioneer has developed a technique which will allow optical drives to store 500GB of data.

That’s according to the Nikkei Business Daily, which reported that the technique will use ultraviolet lasers, which emit shorter wavelength rays than blue lasers. The paper reported that Pioneer uses the beam to write data holes in a master disk, each separated by 70 nanometres. That gives a data rate 20 times more than the blue laser Blue-ray disk. While there are technical problems creating data cavities so small, Pioneer has, apparently, solved problems associated with scattering of the laser by developing a carbon mask using photosensitive resin.

That's HUGE! Why, oh why can't the accepted size for harddrives be this big! They have some that are close, but they're so expensive, like, I assume, this will be, too

11 Nov 2004 ~ 1:29pm Unregistered 500 gb, takes a long time to fill that up unless DVD's burn beyond 16x with fast seek/ write/ re-write times.

good point
11 Nov 2004 ~ 5:30pm TheBaron it takes a long time to fill up a 500gb harddrive too
so?
11 Nov 2004 ~ 5:55pm gibbonsl oh the smu...ani... er stuff i could put on those :o
11 Nov 2004 ~ 6:38pm RWB Plus with the new scratch resistant(or scratch free hehe) stuff that someone came out with recently these will rock even harder!
