Abstract
Three-dimensional positions on an ABS of a slider of a magnetic head are measured, and an interpolated surface is generated by interpolating all the measured points. A processing center position of the magnetic head is calculated based on the interpolated surface, and a plurality of lines parallel with the processing center position are processed. It is also possible to process, by irradiating energy corresponding to a difference between a final target correction volume and a measured value, without forming an interpolated surface.
