Abstract

A manufacturing method for variable shape mirrors suitable for mass production includes steps: for overlaying a pair of jigs 41, 42 having protruding bar portions like comb teeth 41b, 42b on a support substrate 2 so that the protruding bar portions are orthogonal to each other, and inserting support pillars 5 and piezoelectric elements 4 into through hole portions 43 that are formed by gaps between the protruding bar portions, and placing a mirror substrate 3 on the support pillars and the piezoelectric elements; for bonding at least the support substrate and the support pillars, the support substrate and the piezoelectric elements, and the mirror substrate and the support pillars to each other, respectively; for drawing out the jig in the direction opposite to a protruding direction of the protruding bar portion; and for forming a reflection film on an outer surface of the mirror substrate.

Description

technical field [0001] The invention relates to a method of manufacturing a deformable mirror mounted on an optical pickup device. Background technique [0002] Conventionally, compact discs (CDs) and digital versatile discs (DVDs) are available in the market as optical recording media for recording information such as pictures and sounds. Furthermore, in recent years, next-generation DVDs have been commercialized, which use a violet laser beam having a short wavelength to achieve higher density recording. In order to use such an optical disc, an optical disc device serving as a drive device is required. An optical disc device drives an optical disc to rotate, and directs a laser beam onto a recording surface of the optical disc, thereby recording or erasing information and reproducing information based on reflected light from the recording surface. In addition, in order to realize such a function, the optical disc device is equipped with an optical pickup device, which, a...
