Abstract

See full text

In an approach for providing simulation results of an interaction between a transducer head and a magnetic medium, a computer identifies a first raster scan of a sample via a scanning probe microscope. The computer generates a topography image based on the first raster scan of the sample. The computer identifies one or more reference features within the created topography image. The computer calculates an average height based on the one or more reference features. The computer determines a lift distance associated with a probe of the scanning probe microscope. The computer defines a uniform plane based on the calculated average height and the determined lift distance. The computer performs a second raster scan of the sample based on the defined uniform plane. The computer generates a fly-height image based on the second raster scan. The computer provides simulation results based at least in part on the second raster scan.
