If you actually have diskettes from that era that you care about, you might want to image them using a low-level magnetic flux reader - the devices are actually quite inexpensive, and this would ensure that the data is preserved for the foreseeable future.

Well, he said an old MFM drive, so he's probably referring to an MFM hard drive rather than diskettes. That was the common parlance for MFM HDDs back then.

Link? Googling that term shows at most probes that register a single scalar value, not something that can image a diskette. (Nor were those "quite inexpensive")

I wouldn't agree with "quite inexpensive" (start at $100~$200 and then you need a drive as well) but there are some of the options out there for low-level magnetic floppy imaging.
