Re: 3 1/2 inch floppy drive?
"I'm sure there are many on here who remember those ancient storage mediums and capacities."
Not so ancient. They were still being used on mainframes when I retired a few years ago.
When I started as a computer operator in the 1960s the first thing you learned was how to prepare a new tape for use. That involved a very large bottle of acetone in order to remove a small section of the tape coating - to leave a clear window for the optical sensor's start-of-tape positioning. The tape was attached to the take-up spool's leader by splicing it every time with sticky tape.
To keep the two reels rotating at the changing different speeds - a loop of tape was weighed on each side of the read/write head.
The data density was so low that you could read the bits with the window on a little 3M device - shaped like a large thick coin. You held it against the tape surface and tapped it until the contents aligned themselves to show the bits - like iron filings do in the presence of a magnetic field.
