Summary:A data storage medium is introduced. The data storage medium from which information is reproduced by scanning a surface of the medium with a tip positioned in contact therewith comprises a recording layer within which data values are determined by the topographical state at the data item location. The material of said recording layer comprises a component that is generating an etchant. The etchant removes the naturally occurring surface oxide layer of the tip which keeps the tip sharp and works against tip wear.
