Zusammenfassung: | Methods for referencing related magnetic head microscopy scans to reduce processing requirements for high resolution imaging are provided. One such method includes performing a low resolution pole tip recession scan of a pole tip area of a magnetic head, performing a high resolution writer pole recession scan of a writer pole area of the magnetic head, preparing a portion of the low resolution scan for alignment, performing a rough leveling of the high resolution scan, aligning the portion of the low resolution scan and the high resolution scan using pattern recognition and a database of features, subtracting the high resolution scan from the aligned portion of the low resolution scan, and leveling the high resolution scan based on a result of the subtraction. |
