<p>The apparatus includes an objective lens (2) for focusing a laser beam emitted from a laser device (1) onto a magneto-optical recording medium (10), driving coils (3a,3b), on which the objective lens is mounted, for driving the objective lens in focusing (f) and tracking (t) directions, and a plate (8) arranged at an end portion of the driving coils between the objective lens (2) and the magneto-optical recording medium (10). The plate (8) is formed with a coil pattern (7) for generating a magnetic field to be applied to the magneto-optical recording medium (10), and can allow a laser beam transmitted through the objective lens to pass therethrough.</p> |
