Abstract
Systems and methods are disclosed for overlap detection using bitmask region trackers. In an embodiment, an apparatus may comprise a controller configured to maintain a count of writes associated with a selected area of a data storage medium, generate an overlap check bitmask, including an overlap check bit for each of multiple regions of the selected area and that represent an indication of a previous write associated with a respective region from the multiple regions, generate a write check bitmask based on a received write, the write check bitmask including a write check bit for each of the multiple regions of the selected area and representing which of the multiple regions are related to the received write, and increment the count of writes based on comparing the overlap check bitmask with the write check bitmask.
