Magneto-optical data storage system
 A magneto-optical data storage system having a magneto-optical disk rotatably mounted on a support body. The disk has a planar storage surface with a plurality of concentrically disposed data tracks. A flying magneto-optical head is mounted on the distal extremity of an arm pivotably mounted on the support body for aerodynamic suspension adjacent the storage surface during rotation of the disk on the support body. A mirror assembly of micron dimensions is carried by the head for reflecting a laser beam between an optical light emitter and receiver carried by the arm and the storage surface of the disk to permit the optical recording and/or reading of information on the data tracks. The mirror assembly has a planar base and a planar mirror spaced apart from the planar base and disposed generally parallel to the planar base. The planar mirror has a longitudinal axis extending between first and second end portions. The mirror assembly further has first and second hinge members secured to the planar base extending along the longitudinal axis and connected to the first and second end portions. The mirror is rockable between first and second positions about the longitudinal axis relative to the planar base and at least a portion of the mirror is of a conductive material. The mirror assembly has first and second spaced-apart electrodes carried by the planar base for driving the mirror between the first and second positions.
