摘要: A driver in a far-field magneto-optical (“MO”) system has read/write head that includes an objective lens for focusing laser beam onto MO disk. The is housed holder. magnetic biasing coil mounted to the bottom of holder, between and aperture allow pass through surface holder moved up down as disk spins by actuator maintain focus on surface. This maintains precisely at predetermined distances from surface, despite irregularities wobble.
