To generate a high data transfer rate from a magnetic write head, a faster flux rise time is needed. This often brings about severe excess saturation of the head and, as a result, adjacent track erasures often occur. This problem has been overcome by indenting P 1 away from the ABS so that there is a narrowing of P 1 near, but not all the way to, the write gap. This causes the excess flux associated with high write currents to be diverted into P 2 instead the P 1 shoulder.
