The obsolescence of either is enough to render your data unrecoverable.
Physical media seems to die out sooner than file formats do simply because
it's generally not too hard to keep a file format reader around in
software. As you found with ImageMagick. Thank goodness for that at least.

I actually own an 8-bit paper tape reader, 110 baud, chunky mechanical
thing with a big motor. The last time I used it to read tapes I cobbled
together a 20mA current loop to RS-232 converter and transferred a bunch of
data to floppies.

If I wanted to use it today I'd like to have a 20mA current loop to
Bluetooth interface but I don't imagine they are too plentiful.

BTW, the last time I used that reader, I also had to write a DEC PDP-8e
emulator to run the code on them. Some of the tapes are in RIM format and
some in BIN, all with code from the late 1960s and early 1970s. 'Twas a gas
to see the old FOCAL prompt again.
