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.
