I'd bet the oxide is coming free of the substrate and causing the
screeching sound. That is just surmise.
I spent about a week rejuvinating a 9track tape that was doing something
similar. I kept cleaning the heads and running the tape through the drive
while holding alcohol soaked chemwipes to the tape surface. I'm unsure if
you can clean a floppy this way or not.
