Abstract

See full text

A flying height tester that can vary an air pressure and measure an air bearing height between a slider and a substrate. The substrate is located within a chamber that has an air pressure. The tester includes a loader which places a slider adjacent to the substrate. An optical system computes the air bearing height from a light beam that is directed through the substrate and reflected off of the slider. The chamber is coupled to a pressure control system that can vary the pressure of the air surrounding the slider. The pressure control system varies the pressure to simulate slider operation at various altitudes. The tester of the present invention can thus measure air bearing height while simulating various altitude conditions.
