They look a lot like hard drives, but apparently
the arm isn't as rigid as a modern arm. And the air pressure
under the head might be different as well (as a cushion).

It's too bad there wasn't NAND flash back then.

I wonder if floppy diskettes would have been a good option for a submarine ?
They could have used a machine with "dual floppy", as that is a handy
setup for making backups. The "single floppy" computers were a pain in
the ass, to clone a floppy. The RAM on the computer is not big enough to
hold the floppy contents, and copying an entire floppy required flipping
in disc 1 and disc 2, over and over again, until the transfer was finished.
When a machine had two floppy drives, it "was like Heaven" :-)
