Side shield pedestal for data readers

摘要

Various embodiments may be generally directed to a magnetic element capable of reading magnetic data bits. Such a magnetic element may have at least a magnetic stack laterally adjacent a side shield and non-magnetic pedestal on an air bearing surface (ABS). The non-magnetic pedestal can be configured to have a greater stripe height from the ABS than the side shield.

主权项

1. A data reader comprising a magnetic stack having a free layer laterally adjacent a side shield and non-magnetic pedestal, the side shield and non-magnetic pedestal each positioned on an air bearing surface (ABS), the magnetic stack including the free layer having a first stripe height, the side shield having a second stripe height, and the non-magnetic pedestal having a third stripe height, the first, second, and third stripe heights each measured from the ABS, the second stripe height being smaller than the first and third stripe heights, the non-magnetic pedestal continuously extends from the second stripe height to the first stripe height, the first and third stripe heights being the same.
