The floppy drive has a stepper motor that controls the placement of the read/write head above the disk.
In the ST era, the control of that motor was directly under the control of the operating system. For an 80 track disk, the movement required to step between tracks was a certain known amount.
If you formatted the disk with the tracks spaced closer together, by altering the stepper movement during that process, you would 'magically' get more space.
