Not so, servo tracks have position information encoded within them - the
drive knows when it is at the correct servo track

If you *write* the servo signal and you're off by 0.0020" one way, and 
then the next time you go to find the track, you're off by 0.0020" the 
*other* way, then the servo track is 0.0015" out of range - and you 
can't find the track anymore.
Even worse, if the next track over is *also* out-of-spec, you can end 
up accidentally aquiring the servo signal for the *wrong* track.  
Whoops. ;)
