I meant as a viable home project, doesn't have to be a fully functional drive as long as it somehow allows to view the magnetic values, manually turn their 2D structure into the valid 1.44MB filesystem if necessary :)
- djmips 8y agoYes. You could make your own magnetics value reader which would also be a functional drive but perhaps not 'fully' in that it might be slow etc. For example you could make a high resolution x,y table with a read head that made a flux map and the you could post process this into the data. Using an existing floppy drive seems so much more practical for the job of data recovery.
- rasz 8y agoFloppy drive does not decode disk data on its own, it merely amplifies analog signal from magnetic head, filters and quantizes it (zero crossing). https://patents.google.com/patent/US4656533A/en https://patents.google.com/patent/US4656533A/en What you get on a READ pin of floppy drive is the same information you would probing read head (or rather preamp) using Oscilloscope. All you are interested in is magnetic field flipping, zero crossing, encoded on READ pin as an impulse. Sure, you could precision machine turntable like contraption to do it manually, but floppy drives are plentiful and practically free.
