Abstract:
A method of measuring attitude angles of a tongue of a head suspension, the tongue including a fitting face on which a plurality of electrodes are arranged, emits a single collimated laser beam to an area of a fitting face containing at least two of electrodes, detects a reflected beam from the fitting face, extracts electrode reflective components corresponding to the electrodes from the reflected beam, and according to the electrode reflective components, measures the attitude angles of the tongue.
