Magnetic read/write heads 1 and 2 of a disk file are located at the tips of a dual head support arm 3 of "V" shape. The support arm 3 is mounted for axial rotation on output shaft 4 of a rotary actuator, such as described in U. S. Patent 3,849,800. Rotational balance can be achieved by using electronic packaging as a counterweight (not shown) so that the rotating mass has a "Y" configuration.
