Abstract
A method is provided for fabricating a slider out of a production piece slider blank so that the slider may be used in a glide head assembly that is operative with a test system to detect a presence of asperities on a moving surface. Broadly, this method comprises configuring an air bearing structure on the production piece slider blank to form a working production piece having an unpolished air bearing surface and an outer sidewall surface which intersects the unpolished air bearing surface at a pheripheral edge. The unpolished air bearing surface is lapped to form a polished air bearing surface which is microfinished to a selected ABS Ra value. A region of the outer sidewall surface adjacent to the pheripheral edge is also lapped to form a sidewall margin area that is microfinished to a selected sidewall Ra value that is within a range of about ten times the selected ABS Ra value, thereby forming a finished production piece.
