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.
