Abstract:
A disk drive, comprising:a disk having a recording surface; a ramp structure defining a ramp surface; a head stack assembly including: an actuator body; an actuator arm cantilevered from the actuator body and including a head for reading and writing on the recording surface, the head resting on the ramp surface when the disk drive is non-operational, 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 leg and the second leg, the damping magnet being configured to exert a damping force on the head stack assembly, the damping force being greater when the head is on the ramp surface than when the head is over the recording surface.
