Actuator, Optical Pickup, and Disc Apparatus

Abstract

Provided is an actuator, an optical pickup, and a disc apparatus, with improved assembling workability and reduced manufacturing cost. The actuator of the optical pickup of the disc apparatus includes a movable part and a fixed part supporting the movable part in a movable manner. The movable part includes a case and a plurality of drive substrates having the same specification. The drive substrates are disposed at positions opposed to each other with respect to the case. Each drive substrate includes a winding member for driving the movable part and a wiring pattern for supplying current to the winding member. The wiring pattern includes a plurality of electrodes and a conductive path. The electrodes are disposed at positions opposed to each other with respect to the winding member. The conductive path is branched from one end of the winding member and is connected to the electrodes.
