摘要： A data storage device is disclosed comprising a first head actuated over a first disk surface, the first head comprising a plurality of elements including a first element. During a first write operation of the first head, a first bias signal having a first polarity is applied to the first element, and a write interval of the first write operation is measured. During a non-write mode of the first head, a second bias signal having a second polarity opposite the first polarity is applied to the first element during a reverse bias interval that is based on the write interval of the first write operation.
