ABSTRACT:
There is provided a head gimbal mechanism2including a slider10placed between a recording medium D and a beam11and having a device generating near-field light, gimbal means12for fixing the slider to the tip of the beam11at a state that it can rotate about two axes which are parallel to the surface of the recording medium and are orthogonal to each other, and a flexible optical waveguide13composed of a basic waveguide section21placed along the beam and a bent waveguide section21that is bent in the Z-direction substantially orthogonal to the surface of the recording medium from the tip of the basic waveguide and connecting to the slider in non-contact with the beam and the gimbal means, the optical waveguide13guiding the luminous flux to the slider, wherein the basic waveguide section is placed at a state that at least a predetermined length on the bent waveguide section side relative to the beam is not fixed to the beam.
