Mega-DVDs -- 100GB Apiece

Articles can be found here(1) and here(2)." 100GB on a disk would be a nice way to store backups -- but since the DVD consortium hasn't made any promises, this format may remain just a demo technology forever.

  1. Violet Laser != DVD by Diesel+Dave · · Score: 4, Informative

    First: It a sad thing *ANY* article on slashdot is consumed by dog shit posts. 20 comments already attached to this article and not a damn one has anything to say.

    That said the real story here is the wavelength change. Normal CD's are red lasers. DVD's are blue. This thing is VIOLET. The shorter the light wave, the more dense the data can be. So this is big news because it is a new level of technology, not a progression of one of the current technologies. (Without question some form of this will be adopted)

    This means that some of the recent tricks (multi-layers) will probably be applicable to this to yield a VERY high amount of storage, maybe 100-200GB per side. That is of course if they don't come out with an ULTRA-VIOLET laser based system first. (Uhmm does an ultra-violet laser even exist yet??)

    OK guys we're at 50GB per platter now. Give me random I/O of 4ms, and I'll chuck my magnetic HD's out of the window.
