What kind of balance are we talking about?
It's not the device that worries me but the disk itself. It has a magnetic strip in it where the data is stored, like early analog photo cameras.
One small scratch or some dust particle sets on that magnetic strip, and your are fucked, the data will become unreadable.
It is inevitable for floppy to become degraded, that is why nobody uses it anymore, its very inefficient and faulty.
I remember cleaning my floppies in the 90's, you had to use a special solution to clean the dust particles off, but still, no guarantees. It will become corrupted eventually.
Better use CD or DVD, at least there the data is burned inside deeply, and not on the surface, so dust particles affect it less.
