发明名称 MAGNETIC HEAD INSPECTION SYSTEM AND MAGNETIC HEAD INSPECTION METHOD
摘要 The magnetic head inspection method includes, exciting the cantilever of a magnetic force microscope at a predetermined frequency, the cantilever being provided with a magnetic probe on the end thereof, floating the magnetic probe over the writing head of the magnetic head and two-dimensionally scanning a search range, detecting the specific position of the writing head based on the search two-dimensional magnetic field intensity of the writing head with exciting state of the cantilever in the two-dimensional scan, setting a shape detection range smaller than the search range for detecting the shape of the writing head based on the specific position, and floating the magnetic probe over the writing head with exciting state of the cantilever, detecting the shape of the writing head by detecting the detection two-dimensional magnetic field intensity of the writing head in the two-dimensional scan.
