I remember buying MO disks in 1994 (3rd grade) for my Performa, only to be disappointing when I learned that I needed a special drive. Does anyone know what MO/floptical drives work with System 7? Does it mount like a floppy?

I can't remember the difference (if there is one) between magneto-optical and floptical, but it is a format that intrigues me. I use System 7 for all my writing, so I use floppies and Zips for backup. How reliable is MO?
