Abstract
A data storage device includes at least one data storage medium having a plurality of tracks. The data storage device also includes at least one actuator that supports at least one head that is configured to interact with different tracks of the plurality of tracks on the at least one data storage medium to service commands from a host. The data storage device further includes a seek control circuit communicatively coupled to the at least one actuator. The seek control circuit is configured to store the commands from the host in at least one queue for execution by the at least one actuator. The seek control module is also configured to adjust power provided to the at least one actuator for seek operations to the different tracks of the plurality of tracks based on command age-related measurements of the commands from the host.
