Abstract
An apparatus can be generally directed to a magnetic stack having a magnetically free layer positioned on an air bearing surface (ABS). The magnetically free layer can be biased to a predetermined magnetization in various embodiments by a biasing structure that is coupled with the magnetically free layer and positioned distal the ABS.
