Abstract
A slider lapping texture for implementation in a lapping environment. The slider lapping texture includes a lapping texture structure for utilization in a lapping process performed on a slider. The structure also includes a first surface having a base elevation. The structure further includes a second surface at an elevation higher than the base elevation. The second surface is for lapping the slider. The structure additionally includes an opening for expelling residue associated with a lapping process. The slider lapping texture is configured to generate an attractive force when the slider is motioned thereupon in a substantially unidirectional manner.
