Abstract
A flexible printed circuit board using a lead-free solder is to be fixed within a disk enclosure while ensuring a high rigidity. In one embodiment, a rotating disk storage device comprises a flexible printed circuit board (FPC), wherein there is formed a wiring pattern including a signal line for the transmission of a signal of data read by a head in an actuator head suspension assembly (AHSA) and wherein one side end portion is fixed to a base and an opposite side end portion is fixed to the AHSA. A first metallic plate and a second metallic plate are both fixed to one side end portion of the FPC. A connector is disposed in an area where the first metallic plate in the FPC is provided, and connected to the wiring pattern. A shock sensor is disposed in an area where the second metallic plate in the FPC is provided, and connected to the wiring pattern. A reinforcing plate of a synthetic resin is, in an opposed state of the first and second metallic plates fixed to one side end portion of the FPC, held between the opposed faces of both metallic plates and is fixed to the base together with both metallic plates.
