摘要
A technique implemented by a processor may include controlling a write head to write data to at least one partition of a data track of a magnetic data storage medium. The data track may include a plurality of partitions. The technique also may include determining, for each partition of the at least one partition, whether the partition has been previously written to by inspecting a partition overlap register associated with the data track. The partition overlap register stores a respective entry for each partition indicating whether the partition has been previously written to. The technique also may include, in response to determining that at least one respective partition of the at least one partition has been previously written to, incrementing a damage counter of at least one adjacent track and resetting each entry of the partition overlap register to indicate that each respective partition has not been previously written to.
