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.
Is this just a gimmick by companies to get funding or something?

For backups at least ina profesionnal environement you need more speed. writting DVD is slow compared to technologies like LTO, which stores up to 200 Gig on a casette.Archives which you write and then store somewhere in a safe palce because You personaly don't need the data, are better stored on worm devices like DVD's. French quality commette recommends Worm device writting for archives you need to keep for the IRS.

For those of you not in the know, Matsushita is the Japanese parent company of Panasonic.
With all of the other fanciful storage media (FMD, anyone), we're talking about tiny start-up companies that are throwing (usually) empty promises out about their newest gizmo because, let's face it, they'll do anything to jack the stock price a little.
I would feel safe in making a bet that we would never, ever see widespread use of FMD (maybe something similar, but probably never FMD). I just don't think a company that small would have the financial resources to tangle with the big boys on something as big as a common media storage format.
Meanwhile I sit here looking at my Panasonic television. I saw their Home theater DVD-R unit at the electronics store today for $1K. Call me crazy, but I just find this claim a little more legit than most.
MPAA Meeting: Great, so now we have to give those ungrateful consumers higher quality video with less compression... no screw that, lets just put 40GBs of copy-protection systems on.
I would actually _pay_ (yes, me actually pay real money) for DVDs that used all this capacity to give me extra high-quality data with less compression. Instead of downloading crappy DivX'ed versions. Seeing DVDs now, i don't understand how anyone could be fooled into thinking they are high-quality, the artifacts are terrible

Yes, UV lasers do exist, but they're not the nicest of things. Firstly, like IR lasers, they're invisible, but unlike IR lasers, they tend to scatter and diffract off surfaces very easily, due to the high wavelength. So you never really know where they are.
Secondly, UV lasers have a nasty habit of causing cancer on contact with the beam. Granted, only a very low power beam will be required to read the media, but I bet the average consumer will be thrilled with having invisible carcinogenic radiation inside their computer.
On a vaguely related note, due to the ionising nature of UV lasers, they're considering making tasers out of them. I spose the thinking is, if they don't incapacitate the criminals, they'll give them cancer. I see a great case for lawsuits here....
