Hiding data on 3.5" using "40 track mode"

[Travis H.]

In the FBI's public statement about Hannsen, they relate how he used a 3.5"
floppy in "40 track mode" to store data, but if it was read in the
ordinay way it
would appear blank.  IIRC, high-density floppies are 80 tracks per inch, and
double density were 40 tpi.  So, how do you suppose this trick works?
The official details are, of course, vague.
