Abstract

This paper describes a system known as 'The Disaster Detector', for automatic inspection of the air-bearing surface of disk sliders (disk read/write heads). It inspects for certain types of defects that are global or systematic in the sense that, when they occur, they occur on every slider in a row or, in some cases, on every slider in the entire carrier. The inspection system is described and the associated image-analysis algorithms are described in detail. The system uses standard microscope optics, a color CCD camera, computer-controlled state, laser autofocus, a video digitizer and a PC/AT (486-based).
