Abstract
A system and method in which a commercial non-contact optical surface analyzer is utilized to characterize the severity of a head slap event through examination of the surface of a data storage disc. The optical surface analyzer selected has the capability of detecting surface topography using a high-resolution scanning head. When performing the analysis, the data storage disc may be removed from the disc drive and placed on a spindle. The data storage disc surface topography scan takes place while the disc is spinning. A full scan of the entire data storage disc surface can be done, as well as a zoomed scan on a specific area of the data storage disc surface, thereby allowing for a higher resolution scan on the surface encompassing a head slap event. Data captured by the optical surface analyzer can then be exported to a commercial mathematical program for analysis and presentation.
