I recently saw the Sony MSAC-FD2MA. It's a memory stick to floppy adapter. I assume an SD to memory stick adapter would work with it. I'm curious how it works internally. How does it interface with the read/write head? How does it map logical data (files, FS) to sectors and tracks? Or if it doesn't, how does it even map a flat image file? Floppies can be formatted all sorts of ways.
