ABSTRACT:
A magnetic optical recording/reproducing apparatus comprising: a movable focus adjusting member including converging means for converging a light beams emitted from a light source on a focal plane of an optical recording medium, focus coil means for driving the converging means in a direction substantially vertical to the plane of the optical recording medium by electromagnetic force when a current is applied, seek coil means for driving the converging means in a radial direction of the optical recording medium by electromagnetic force when a current is applied, and support means for supporting the focus coil means and the seek coil means; a carriage means for moving the movable focus adjusting member in the radial direction of the optical recording medium; and spring means fixed at one portion thereof to the movable focus adjusting member and the other end portion thereof to the carriage means for supporting the movable focus adjusting member to move the movable focus adjusting member to the carriage means in a direction substantially vertical to the plane of the optical recording medium.
