説明

<p>The objective lens actuator of an optical disk system tilts by varying amounts during operation because of non-uniform component parts, non-uniform assembly,environmental variations, and other such noise factors. Since tilt of the objective lens causes significant deterioration in the performance of the optical disk system, the amount of tilt during operation must be kept within specified limits. Conventional approaches to this problem, such as tighter part tolerances and assembly tolerances, lead to increased cost. A better approach is to design the actuator in full consideration of the variations that may occur in the field,but the more noise factors there are to consider, the longer it takes to work out the design. When simulation ahd quality engineering are combined, a more efficient design method can be obtained and a robust design in which a large number of noise factors are taken into consideration becomes possible. In the present robust design study, the noise factors were assigned to an L128 orthogonal array and control factors were assigned to an L36 orthogonal array. The resulting design improved the functionality of the lens actuator with respect to variable factors in the field, and the amount of tilt during operation was reduced.</p>
