<P>PROBLEM TO BE SOLVED: To provide a wave front aberration correcting mirror and an optical pickup capable of reducing influence on the flatness of a mirror by a temperature. <P>SOLUTION: On the side opposite to the mirror surface of a mirror substrate (6), a point contact material (22) is fixed to a piezoelectric material (2) and a structure (21) for suppressing the deformation of the mirror substrate (6) by thermal expansion through the point contact material (22) is provided. <P>COPYRIGHT: (C)2004,JPO |
