| 英文摘要 | High-performance and reliable objective lens driving apparatus and optical pickup wherein the tilt of an objective lens relative to an optical disc is suppressed are provided. The optical pickup is equipped with a semiconductor laser, an electro-optic component, and the objective lens driving apparatus. In this optical pickup, the objective lens driving apparatus is comprised of: a moving part including an objective lens, a holder that holds the objective lens, a focusing coil, and a tracking coil; a holding member for elastic support members that couples together multiple elastic support members providing elastic support on a fixed part and the moving part and is mounted on the moving part; the elastic support members that elastically support the moving part from the fixed part; and the fixed part. The holding member for elastic support members mounted on the moving part and the holder that holds the objective lens are joined together by fitting together a concavity and a convexity. |
