Rotating memory data recovery

I like this approach in theory. I think it has great long-term
potential for data recovery and preservation for our hobby.

Anyone care to give a thumbnail sketch of what sampling rates
would be necessary to digitize the signals on recording media
(3 1/2", 5 1/4", 8" floppy, hard disks, drums, disk packs, etc.)
at sufficient rates to preserve the encoding for post-processing
in other tools?

I saw one reference online that said 3 1/2" and 5 1/4" floppies
were 250-500 kbit/s. If we were digitizing at a much higher
rate than the original simple circuitry that might've only
detected flux traversals, couldn't we recover more data?
