An actuator arm assembly includes an actuator arm rotatably mounted on a base and having a first surface and a second surface, a first suspension fixed at a base end portion thereof to the first surface of the actuator arm at a front end portion thereof, a first head mounted on a front end portion of the first suspension, a second suspension fixed at a base end portion thereof to the second surface of the actuator arm at the front end portion thereof, and a second head mounted on a front end portion of the second suspension. The actuator arm assembly further includes a first lead wire bundle connected to the first head, a second lead wire bundle connected to the second head, and a projection formed integrally with the actuator arm so as to project from a side surface of the actuator arm in a direction substantially parallel to the first and second surfaces. The first and second lead wire bundles are juxtaposed in the direction substantially parallel to the first and second surfaces.
