发明名称 熱アシスト磁気ヘッド検査方法及び熱アシスト磁気ヘッド検査装置
摘要 <p>An apparatus for inspecting a thermal assist type magnetic head is configured to include a scanning probe microscope unit comprising a cantilever having a probe with a magnetic film formed on the surface of a tip portion thereof; a prober unit which provides an alternating current to a terminal formed on the thermal assist type magnetic head element; a scattered light detection unit which detects scattered light generated from the probe; and a signal process unit which detects defect by using an output signal from the scanning probe microscope unit by scanning the surface of the thermal assist type magnetic head element with the probe in a state that the magnetic field is generated and the near-field light is stopped, and an output signal from the scattered light detection unit by scanning the surface with the probe while near-field light is generated and the magnetic field is off.</p>
