ABSTRACT:
An apparatus for supporting an optical system, in which one of the springs for supporting an objective lens holder is positioned in an incident/reflected light beam extended in a direction parallel to an information recording surface of an information recording medium to close up an objective lens and the light beam, so that the apparatus as a whole can be made compact and thin in a focusing direction. Since the height of the apparatus becomes low, and the members for driving the lens holder, i.e. magnets, etc., can be arranged in an upper side of the apparatus, the moving sensitivity of the apparatus can be improved.
