A new method is introduced for predicting particle and liquid droplet contamination on an air bearing surface. The method primarily relies on the analysis of flow patterns nearest the air bearing surface, restricted to two dimensions. In addition, a mathematical model for the 3-dimensional flow adds clarity to the contamination mechanisms. The predictions compare well with contamination patterns observed in prototype disk drives.
