ABSTRACT:
A method of re-correcting the position of a head is used in a disk driving device including a zero track restoring arrangement for electrically detecting the zero track position on a magnetic disk, and including a track counter indicating the track position of the magnetic head. The method is configured to monitor the track number of the track counter and never fails to effect re-correction of the position of the head when the track number is "0" or "1".
