Abstract
A head gimbal assembly (HGA) for a disk drive is disclosed. The HGA includes a load beam, a flexure, and a slider attached to the load beam by the flexure. The load beam comprises one or more apertures configured to pass a laser beam at each of at least three non collinear points to measure at least one slider parameter. The method for measuring at least one slider parameter includes positioning the slider over a rotating medium and projecting a laser beam through the one or more apertures in the load beam.
