Abstract
It is determined whether one or more heads of a data storage device (DSD) have been within a radial position of one or more disks of the DSD for more than a threshold period of time. When it is determined that the one or more heads have been within a radial position of the one or more disks for more than the threshold period of time, the one or more heads are radially moved by more than a predetermined distance to reduce a development of variations in a distribution of lubricant on a first surface of the one or more disks.
