Abstract

A disk drive includes a disk and a head stack assembly for reading and writing to the disk. The head stack assembly includes a body portion, a first actuator arm cantilevered from the body portion and a second actuator arm cantilevered from the body portion. A coil portion is cantilevered from the body portion in an opposite direction from the first and second actuator arms. An actuator arm spacer is disposed between the first and second actuator arms and away from the body portion, and mechanically links the first and second actuator arms.
