That?s one level of abstraction. Another possibility

view ?digital? data as analog, which of course it actually is, and
capture it at that level. It would take more specilized hardware to
do that, and the files would be a great deal larger, but it would
also capture detail that a digital representation hides. For
example, damaged spots might be recoverable if that is done.
Something like the DSP based tape drive Paul Pierce built (if I
remember that one right) would be a way to capture old media at that
level.
That might be useful if the tape couldn't be successfully read using
conventional means, but in cases where the tape reads BOT-to-EOT
correctly, there's no additional information to be obtained and the
extra effort is of little value.
