ABSTRACT:
A method of determining the close point for a glide head includes measuring the fly height of at least three positions remove from the selected close point position. The three selected positions are curve-fitted and extrapolated so as to obtain the height at the selected close point. Adaptions are made where the glide head can roll and measurements can be taken at locations transversely across the head.
