Methods for referencing related magnetic head microscopy scans to reduce processing requirements for high resolution imaging

Abstract

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.

Dependencies are inferred from the claim text.
