Abstract
Utilizing a time domain correlation algorithm, we observed that the readback signal for media with a soft keeper layer can be shifted from their original written locations in the hard under layer. The shift was similar to the hard-easy transition shift. It results from a change of magnetic charge distribution in the keeper layer in the read process. The effect of the keeper layer on transition shifts in the write process was insignificant
