Abstract
Various apparatus and associated method embodiments are generally directed to a magnetic stack positioned on an air bearing surface (ABS) and biased to a predetermined magnetization by a bias magnet. The bias magnet can be separated from the magnetic stack and at least one magnetic shield by a self-aligned magnetic insulating feature that is comprised of first and second insulating layers.
