Abstract
A Data Storage Device (DSD) includes at least one disk surface and a plurality of actuators for accessing data stored on the at least one disk surface. A workload is determined for each actuator of the plurality of actuators, and a logical to physical mapping is modified based on at least one workload. The logical to physical mapping associates logical addresses of data with physical locations for storing the data on the at least one disk surface.
