I don't know what you consider a 'real' floppy. 

https://en.wikipedia.org/wiki/Integrated_Woz_Machine#History

almost all contemporary CP/M machines and others used some variant of the 
WD chip. It could be programmed with a number of options so many 
incompatible formats sprung up. I had a utility that could read most of 
them except the hard sector schemes.

Years later Woz admitted he more or less didn't have a clue what he was 
doing but eventually got it to work. In the best Apple tradition nothing 
but an Apple could read the floppies.
