Maybe y'all have heard about this project, maybe not. A few years ago there
was somebody who came up with the idea to use mini-DV as back-up medium for
computer-data, because of the transfer-speed. After research they realiseed
that for computer-data the bit-error-rate was too high on mini-DV tape, to
make safe back-ups. With an enormous amount of error-correction data added,
it was to do, but then the extra data overhead didn't really make it worth
anymore to making a back-up on a slower medium.
