Abstract
A system and method for burnishing the edges and corners of hard disk drive sliders uses a combination of flexible tape fixturing and mechanical protrusions located beneath the tape to systematically orient selected slider corners and edges to be exposed to an abrasive in a flexible manner. This solution carefully exposes the sliders even when there is very little clearance between the sliders. A variety of different rounding geometries are achieved by customizing the protrusions underneath the flexible tape. Multiple slider corners and/or edges are exposed to the abrasive at one time for bulk processing. The sliders are oriented in such a way that sensitive structures located on the air bearing surfaces of the sliders are not harmed during burnishing.
