Abstract
A method of machining a complex pattern into the air bearing surface of a magnetic head slider includes the steps of forming a die with a diamond surface which has a pattern which is a reverse image of the desired pattern for the surface of the slider; placing the die with the pattern of the die facing the surface of the slider; placing an abrasive slurry between the die and the surface of the slider; applying a pressure between the die and the surface of the slider; and ultrasonically vibrating the die and the slider reciprocally with respect to one another to cause the abrasive slurry to grind the desired pattern into the surface of the slider.
