Normal floppy drive has essentially an analog interface with almost all digital logic in FDC/on motherboard. So building something that translates it's interface to something more modern is not exactly trivial. I can imagine how to build device that stores low-level images of floppy disks, but that is probably not useful for any kind of data exchange (because there is no easy way to access these images without such device), also such images are bound to be significantly larger (i would expect 2x-3x) than usable capacity of floppy. Storing mountable images would involve relatively complex processing of floppy disk's modulation scheme and synchronization. I haven't seen anything that does this, but it is well possible that such thing exists, but it is not going to be cheap. EDIT: Few years ago I had built something like this (with large SRAM array for storage) as a demonstration of how floppy interface works. It kind of worked, but I abandoned this project before getting it to work reliably or documenting it.
