Abstract
A device may be configured at least with a controller connected to a transducer or transducing assembly that is positioned proximal a data storage medium having at least one thermal asperity or other similar defect. The controller may be configured to select a clearance height above the data storage medium in response to a measured severity of the at least one thermal asperity.
