Abstract
A method comprises sensing for thermal asperities while sequentially scanning a plurality of tracks of a magnetic recording medium in a first direction relative to an inner or outer diameter of the medium. The method comprises halting the scanning at a first track in response to detecting a thermal asperity at the first track, and skipping a predetermined number of tracks in the first direction to a second track. The method also comprises sensing for the thermal asperity while sequentially scanning the plurality of tracks beginning with the second track in a second direction opposite the first direction. The method further comprises halting the scanning at a third track in response to detecting the thermal asperity at the third track, and logging the first and third tracks as tracks between which the thermal asperity is located.
