This data shows the grooves of a stereo, vinyl LP record.
The z-axis (heights) in surface data are commonly exaggerated in order to show detail. In OmniSurf3D choose View > Make 1:1 Aspect Ratio to see a truer representation of the slope of the groove walls.
The song, by the way, is from an Arthur Murray album. At this scale I don’t believe we are violating copyright infringement!
