This is actually only part of the story.
There are two types of skew: hardware and software.
Only single-density disks (with a couple stupid exceptions) ever used a
software skew. Kaypro, Xerox, and the like use hardware skew for double
density.
What Mark is pointing it is that the software does not see any skew since the
disk has been formatted with the skew on it (saves xlation time and memory).
