Fun fact: I only recently found out that regular 1.44MB floppy disks could be formatted to 32MB.

Iron oxide is not what regular floppy disks use. That's probably what the issue was.
I would be very interested to know what material was used and how these magnetic films were created back in the 80s. Please share any info that you have!

While it is a great video, it doesn't seem like he actually made a viable floppy disk in the end. Even if he didn't though, it would have been great to say what was actually achieved in the end: what write density was achieved? Could we write and recover even 1KiB of data?
This fascinating engineer [1] has actually achieved making tapes and floppies from scratch [2].

The Google team used Chisel instead of SystemVerilog. You could consider switching to that if it makes sense for your project.

"In fairness to GPT5, in my career I have indeed encountered PhDs with this level of commitment to their particular blueberry."
Nicely phrased!
