Zusammenfassung:A disk drive conducts signals between read/write heads of a rotor assembly and an electrical circuit board and supplies power to an actuator coil. The disk drive comprises a rotor assembly, a magnetic motor having an actuator coil for rotating the rotor assembly and heads into and out of engagement with a rotating storage medium, an electrical circuit board for supplying electrical signals to the heads and for receiving electrical signals from the heads, and a dual-lead flex circuit for conducting signals between the heads and the electrical circuit board and for supplying power to the actuator coil. The rotor assembly comprises a first extension, a second extension, and a pivot, while the heads are mounted on the rotor assembly. The flex circuit has a static portion from which a first lead and a second lead emanate. The first lead has a substantially L-shaped configuration and in part is integral with the static portion making electrical contact with the electrical circuit board and in part is mounted on the first extension of the rotor assembly. The second lead has a substantially L-shaped configuration and in part is integral with the static portion making electrical contact with the electrical circuit board and in part is mounted on the second extension of the rotor assembly such that both leads extend parallel to each other from their respective extensions on the rotor assembly and the second lead does not interfere with the first lead.
