摘要：
A disk drive includes a disk having a recording surface and a head stack assembly that includes an actuator body; an actuator arm cantilevered from the actuator body and including a head for reading and writing on the recording surface; a coil cantilevered from the actuator body in an opposite direction from the actuator arm, the coil defining a first leg and a second leg and a damping magnet disposed between the first and second legs. The damping magnet is configured to exert a damping force on the head stack assembly that is greater when the head is at a predetermined non-operational position than when the head is over the recording surface.
