Abstract: An apparatus includes a data storage medium having a plurality of tracks. The apparatus also includes a write history buffer configured to store a history of prior write commands to the plurality of tracks. The apparatus further includes a controller communicatively coupled to the write history buffer. The controller is configured to receive a new write command directed to a first portion of a first track of the plurality of tracks on the data storage medium. The controller is further configured to determine whether to update ATI contribution measures from the first track based on the history of write commands to the first track.
