Abstract
A magneto-optical (MO) disc drive including a novel suspension, slider body, airbearing surface, and magnetic head. The MO disc drive includes a fine-focus actuator block including an objective lens, wherein the coarse carriage block moves radially above a surface of an MO disc to position the objective lens. The MO disc drive also includes a flat suspension having a first end and a second end, wherein the first end is fixedly attached to the fine-focus actuator block and the second end is attached to the coarse carriage block. A gimbal is moveably attached to an opening in a surface of the suspension and a magnetic head assembly is attached to the gimbal. The magnetic head assembly is loaded and unloaded by the load/unload mechanism independent of the objective lens and attached to the coarse actuator.
