Here's one way around that problem: read it only once, but record the
analog signals from the tape head. Then you can "virtually" read it many
times in software while experimenting with both low-level and high-level
It's not easy, but I've used that scheme to successfully recover data
from many old 7- and 9-track open reel mag tapes. See this GitHub
repository, which is somewhat stale and due for a refresh with the latest
I've not tried it with cartridge tapes, but it seems like it would work
for them too.
