This goes back at least as far as soft-sectored 8" diskettes
in the CP/M era.

IIRC, physical sector 0 of each track contained the C number,
possibly the H, and a list of the remaining sectors on the track
including the size of each sector -- even within a single track
the sectors did not all have to be the same size.
