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
