An actuator assembly including a head actuator, a read/write FPC band, and a relay FPC. The head actuator includes an actuator arm with both a recessed step and a non-recessed surface on a mounting side thereof. The read/write FPC band has an end portion thereof disposed within the recessed step, such that the outer surface of the end portion of the read/write FPC band is aligned with the non-recessed surface. The relay FPC is attached to the non-recessed surface of the actuator arm, such that a connection area of the relay FPC is superposed upon a connection area of the read/write FPC band. Preferably, the connection area of the relay FPC and an area of said relay FPC attached to the non-recessed surface lie along a single plane. Such an arrangement eliminates a step or bend near the connection area of the relay FPC, allowing for simplified positioning of the relay FPC, as well as improved positioning accuracy.
A disk unit including a head actuator having an FPC circuit mounting surface on which a land area with a connection pattern of a read/write FPC band extending from a base side is superposed fixedly for connection on a land area with a connection pattern of a relay FPC mounted on a head side, wherein
