<p>An actuator system for a record and/or read head. The head is mounted in a structure which is movable in multiple directions around a pivot point (72). The head is mounted to an end of the structure opposite the pivot point. The actuator system is preferably used with a stationary media (5) which has a curved surface in the shape of a portion of a sphere with the center of the sphere being the pivot point of the actuator. The head is preferably an optical head with an objective lens (4) mounted at the end of an elongated actuator arm structure (70) which pivots around the pivot point. The remaining optical elements and the emitter (82) and detector (88) of the optical system are mounted farther up on the structure so that their weight is closer to the pivot point to reduce the inertia of the actuator arm.</p> |
