Disk file servo systems using sectored position information typically must derive track-crossing information indirectly during the seek mode. This usually involves building a hardware model of the system to simulate track crossings. Track-crossing information is vital during the seek, in that it provides an accurate means for calculating the distance yet to be traveled.
