Abstract
A head gimbal assembly has a suspension configured to extend along a surface of a recording medium and to bend and deform in a thickness direction of the recording medium. A slider is provided on a front end side of the suspension so as to confront the surface of the recording medium. A support section supports the slider such that the slider can pivot about two axes parallel to the surface of the recording medium and perpendicular to each other. An optical waveguide is connected to the slider and is configured to introduce a light flux into the slider. A near-field light generating element generates near-field light from the optical flux and causes the near-field light to record information on the recording medium. A positioning section is mounted between the support section and the slider for positioning the optical waveguide relative to the slider.
