Can DV Firewire Video Camera's be used for Data Storage? I have a sony

QUESTION:Hey guys, I know this may sound like a silly question but...
Can DV Firewire Video Camera's be used for Data Storage? I have a sony
vx2000 and after all its digital, ones and zeros... why could the camera be
used simply to store data/? If it can, then can anyone suggest any software
to allow this magic to occur?
ANSWER: They ARE used for data storage. What do you think DV video is?
Trouble is, the form of error correction is not good enough for "data"
storage the way you mean it. DV video (and CD audio, for that matter) have
"lossy" error correction. It is good enough to make up for a few lost
samples of audio or video because it goes by so fast you don't notice it.
Actually in DV, when you start loosing too many bits, the blocks of
replacement data start getting larger and larger until you can see them as
blocks on the screen. It is exactly the same "loss of information" method
used to obscure faces on some TV shows. You take a 10-pixel square area of
the picture and average all the brightness and color and replace all 100
pixels with that one value.
But for computer data, the data stream has to be PERFECT. No reason you
couldn't do this with the DV tape format, but you couldn't get as much data
on it because of the space it would take for "data-quality" error
correction.
For example, if you take 74 minutes of audio, you can write a full 74-minute
audio ("Red Bood") CD. However, if you take the SAME data files (WAV or
whatever), they will NOT FIT on the same CD because of the "data-quality"
error correction.
