Optical pickup device and optical disc device with such optical pickup device mounted thereon

Abstract

An optical disk apparatus according to the present invention includes an optical pickup device and a control section for controlling an operation of the optical pickup device. The optical pickup device includes a plurality of first wiring lines for transmitting signals from the control section, a second wiring line to be used for an adjustment of the optical pickup device, and a connector section which is electrically connected to the first wiring lines. The optical disk apparatus further includes a flexible printed wiring board (FPC) which is connected to the connector section for electrically connecting the first wiring lines to the control section. The FPC includes a plurality of third wiring line for electrically connecting the first wiring lines to the control section, such that a pitch of the plurality of third wiring lines in a central portion of the FPC is broader than a pitch of the plurality of third wiring lines in a region of the FPC adjoining the connector section. Moreover, the connector section is electrically connected to the second wiring line, and the FPC being connected to the connector section electrically connects the first wiring lines to the control section, but does not electrically connect the second wiring line to the control section.
