I didn't explain myself well. I used to format high-quality diskettes
in the early 1990s as 21-sector instead of 18, and I consistently saw
errors after about a year of storage on the inner tracks (and never on
the outer tracks). I wasn't speaking from a storage standpoint, but
rather from a reliability standpoint.

If I were to
implement some additional-storage format, I'd probably put
more/larger sectors on the outer tracks where there is more surface
area. I believe Mac and Amiga formats did this, although I'm not aware
of the particulars.
With PC hardware, the sector size is irrelevant with respect to inner
versus
outer tracks. 3.5 inch drives have a constant RPM and a constant write
clock
