ABSTRACT:
A disk drive includes a disk, a head, an actuator, and a servo controller. The servo controller controls a movement of the actuator based on a super silent seek profile to cause the actuator to perform a super silent seek in which an acoustic output due to the movement of the actuator is imperceptible to human listeners. A maximum jerk of the super silent seek profile may be less than a maximum jerk of a silent seek profile divided by ten. A snap associated with the super silent seek profile may be always less than a particular snap level, such that any change in the jerk associated with the super silent seek profile is gradual. The disk drive may further include a main controller that is configured to receive a command from an operating system, a user, and the like to perform a seek in a super silent seek mode.
