The .nib format is nothing but a raw dump of the nibbles from an
Apple II diskette.  The start of the dump of each track should be in
the gap between two sectors, including several sync bytes before the
sector header starts.  Also, each track in a .nib file has exactly
the same number of nibbles -- this is usually not true for physical
diskettes.
 
Download a .nib file and examine it!
