The floppy disk has an "index" hole and
sensor.
HARD sector disks have one hole per sector.
SOFT sector disks have only one hole, and divide the track into sectors in
software.
. . . and Apple and Commodore used soft-sectored, but do not use the index
hole, so the track can begin at any rotational position.
Stringy Floppy is best forgotten.
