Abstract
A head gimbal assembly comprises a slider having reproduction/reproducing elements for reproducing and recording information to/from a surface of a recording medium. A suspension flexibly supports the slider opposite to a surface of a recording medium. A light source is disposed on the suspension for emitting a light beam. An optical waveguide is disposed between the slider and the laser light source for introducing a light beam from the light source into the slider.

A head gimbal assembly for a rotary member mounted on a pivot shaft to undergo turning movement relative to a magnetic recording medium undergoing rotation in a preselected direction, the head gimbal assembly comprising:
- a support configured to be supported by the rotary member;
- a slider attached to a distal end of the support for confronting a surface of a magnetic recording medium;
- an optical waveguide connected to the slider for introducing into the slider light with which the magnetic recording medium is heated;
- a light source disposed on the support for emitting a light beam that is irradiated onto the optical waveguide;
- and
- an electric wiring for supplying power to the light source and the slider.
