Abstract
A servo burst recording and servo control method for a magnetic storage device having a magneto resistive (MR) head comprises the steps of recording an additional burst signal having a magnitude as large as the quantity of track shift caused by a displacement angle of the MR head around each center line of each track, and using the additional burst signal as position identification information for the MR head during servo control thereof. The additional burst signal can be used during a read operation only or during a write operation only.
