Zusammenfassung:A data storage device is disclosed comprising a first head actuated over a first disk surface, wherein the first head comprises a write coil and a write-assist component. First data is written to the first disk surface using the write coil and the write-assist component of the first head. An electrical bias is applied to the write-assist component of the first head to physically damage the write-assist component, thereby rendering the first disk surface read-only.
