How does it work?

It’s nothing new and it’s quite simple. The sound comes from a magnetic head moved by stepper motor. To make a particular sound, head have to be moved with applicable frequency.
FDD has a easy interface – the outline could also be discovered for instance [ HERE ]. To maneuver the top it is advisable to activate the drive by pulling the DRVSB0 or 1 (is determined by the cable you may have and the connector – discover the crossover on the FDD ribbon cable) pin low after which falling edge on STEP pin makes the top transfer one step in route depending on DIR pin state.
An ATMega microcontroller is producing these frequencies and it makes the drives play music.
