Abstract
Embodiments of the present disclosure include methods and systems of lapping a row bar of sliders, where the systems and methods use externally mounted laser components to focus laser energy on an area of an individual slider that can absorb the laser energy in a manner to cause at least the write pole and/or reader to protrude more relative to one or more other slider components (e.g., a reader) during lapping.
