Abstract: A deformable mirror device compensates the spherical aberration caused by the difference of thickness of the cover layers covering recording layers of an optical disc. Circular projections are concentrically arranged on a flexible member (2) where a mirror surface (3) is formed to produce a strength distribution pattern (2a). Attractive force is generated as electrostatic force between an upper electrode (8) and a lower electrode (9) according to the voltage applied from a drive circuit (10) so as to contract the second space (7) and accordingly expand the first space (5) in order to deform the mirror surface. At this time, the profile of the mirror surface is deformed to show a desired profile that can compensate the spherical aberration by the pattern formed on the flexible member (2) as strength distribution pattern (2a). With this arrangement, only a single drive actuator (10) is needed to deform the mirror surface to simplify the configuration and the control operation.

Abstract: Provided is a method for making a double-walled yoke that allows an inner yoke (4) and outer yoke (3) to be integrally joined to each other both easily and securely. Such a yoke provides an adequate cross sectional area for a magnetic path of the yoke while minimizing the weight of the yoke. A tubular member (14) destined to be form the inner yoke and a cup-shaped member (13) destined to form the outer yoke are both fitted on a punch (7) and a drawing process is executed by using an appropriate drawing die (8). The outer yoke may have a small wall thickness as long as it is capable of retaining its shape during use or supporting a bearing for the motor. The inner yoke is required to be relatively small in size as long it is capable of forming a satisfactory magnetic path for the motor. A satisfactory magnetic path can be obtained if the yoke is provided with an adequate wall thickness so as to provide an adequate cross sectional area for the magnetic path.
