Description
The off-track performance of magnetic recording heads is a key issue in achieving high track density. In this study, the position error signal (PES) and off-track capability (OTC) were calculated for spin-valve heads. The position error became large when the direction of the exchange bias field deviated and was disordered in the pinned layer. The OTC also as increased the deviation angle of the disordered direction of the exchange bias field decreased. Therefore, an angular deviation of less than 10 degree is necessary to obtain reliable tracking.
