Pickup device and disk drive

摘要

A pickup device employing an inexpensive flexible printed circuit sheet (FPC) which demonstrates preferable electrical characteristics. FPC has a signal conductive layer inside, and a U-shape bending portion is formed in a midway of FPC at a position where a hologram unit is connected. An opening is formed on FPC adjacent to an area when the hologram unit is connected, and the length of this opening is longer than the height of the hologram unit.
