Patent ID: 8817413

Claim:
A data storage device (DSD) comprising: one or more disks including a first surface for storing data, the first surface having a lubricant distributed thereon; one or more heads for writing data on the one or more disks and for reading data from the one or more disks; a voice coil motor (VCM) for radially moving the one or more heads in relation to the one or more disks; and a controller configured to: determine whether the one or more heads have been within a radial position of the one or more disks for more than a threshold period of time; and when it is determined that the one or more heads have been within the radial position of the one or more disks for more than the threshold period of time, control the VCM to radially move the one or more heads by more than a predetermined distance to reduce a development of variations in the distribution of the lubricant on the first surface.
