So a 4 hour video tape could carry like 60MB if your data is correct.

If your numbers are anywere near correct (others have quoted values of
1200 or 2400 bits per second, but these are for the ancient devices
from 1982 or so) I think I would actually be interested in such a
driver. I also have no backup device and floppy disks are a nuisance;
but if I could get just the core of my system backed up rather easily
(though slowly) I would probably consider doing it.
