Debris Growth And Migration In The Slider-Disk Interface
Slider-disk interface contamination accelerates wear and head crash. It also affects the magnetic spacing. Zhang and Bogy [ 11 reported that small, air-bome particles follow the stream-line closely. They proposed to reduce debris growth at the trailing end by diverting the stream-lines. This paper focuses on relatively large debris in contact with both the slider and the disk. These debris are directly responsible for the wear and spacing-variation. Their growth and migration are dominated by contact forces. An analytical model and experimental results will be presented,
