By 'out', I assume you mean towards higher numbered tracks -- that is
with the head closer to the spindle.

I can see no obvious reason why you'd get more errors on inner tracks if
the alignment was off. The errors would be on all tracks I would think.
Unless your leadscrew is so warn that the head is not properly postiioned
(I have _never_ seen that happen).
A worn/dirty head might give more errors on the inner tracks where the
bit density is higher (shorter tracks), though.
