Abstract
The invention relates to a method of determining wear of a data storage medium actively by performing a read operation on the data storage medium and detecting a read signal, comparing the read signal to at least one wear threshold; and determining a wear level of an area of the data storage medium based on the comparison. The wear threshold is lower than a detection threshold, wherein the detection of the read signal above the detection threshold indicates the presence of stored data.
