Abstract:

A head gimbal assembly for recording information on a recording medium by near-field light is provided with a slider, an optical element which supplies the light to the slider, an optical waveguide which guides the light from the optical element to the side facing the recording medium, and a slider light guiding function part which is formed to extend from a surface provided with the optical element to a surface facing the recording medium of the slider. Also provided are a head gimbal assembly inspection method comprising the step for causing the light from the optical element to enter the slider light guiding function part and determining, using the light emitted from the slider light guiding function part, whether the optical waveguide is nondefective or not, and a head gimbal assembly manufacturing method comprising the step for aligning the optical element and the slider using the light emitted from the slider light guiding function part.
