It is my understanding that proper usage speaks to interleave on a disk
surface, and skew speaks to the positional relationship of corresponding
sectors on different surfaces.  That is, interleave is intended to allow for
processing time that the controller needs after reading one sector and before
reading the next.  Skew, somewhat similarly, is intended to account for the
processing time that the controller needs when switching read heads.
