Abstract
Systems, apparatuses, and methods use angular position tracking in mitigating data loss risks stemming from adjacent track interference (ATI), wide area track erasure (WATER), and/or other issues. A storage device includes a rotational magnetic storage medium divided into a group of tracks and a controller communicably coupled to the rotational magnetic storage medium. The controller is configured to: determine, based on an angular position of a write operation within a group of tracks, whether the angular position of the write operation overlaps a previously written area in the group of tracks; in the event the angular position of the write operation overlaps the previously written area in the group of tracks, increment a counter; and in the event the counter exceeds a counter threshold, perform a data loss risk mitigation procedure.
