Whenever we uncover promising new research into lasers, we can generally be sure that it will sound really awesome, and that it will be a long time before it trickles down to the consumer electronics scene (if ever). That said, research into light powered computing has shown considerable promise -- with some folks estimating that commercial laser-drive hybrids (with picosecond pulse lasers doing the work that magnetic read/write heads once did -- something considered impossible until very recently) will be available in five years time. Although the first drives will only achieve a humble 1 TBits/s, in the future we might see femtosecond-based laser drives reaching speeds beyond 100TBits/s. And you know what they say... that's a lot of terabits.
for reading and writing that fast you dont necessarily need to spin the disc faster, merely use a mirror at the focus point suspended and moved by electromagnets to redirect the focused beam to where the data is, then use a parabolic mirror to focus all reflected light to an optical sensor to pick up the variances in data... viola
Yes, true, there are an infinite number of worse ways of doing it.
I will admit that it isnt the best way, its just one of the easier ways to think of, of course one could always use a system similar to dlp with a transparent, non-moving surface and a sensor behind it.
Considering how large a fs laser spectrometer is, I wouldn't think that this would be released any time soon.
If you read the article it explains that part!
u have no idea how much i would pay for that. that's really fast...
Tbits/s describe transfer rates. I think access times are just listed simply as time, for example: seconds.
(looks at picture)
?????????????????????????????
(i'm sorry, but I cant keep up with that.)
What the heck is a "shark"?? I thought It was what bad TV shows jumped over, back in the 70's!
For a writer on tech site it is an utter embarrassment to not know what access time and transfer rates are. You are an embarrassment.
