ABSTRACT:
An optical head for information recording and/or reproduction has a light source, a deflecting mirror, an adjusting mechanism and an objective lens. A light beam generated by the light source is deflected by the deflecting mirror to be directed to a recording and/or reproducing surface of a recording medium while adjusting the position of the deflecting mirror by the adjusting mechanism. The light beam deflected by the deflecting mirror is converged on the recording and/or reproducing surface of the recording medium by the objective lens.
