ABSTRACT:
A data storage medium includes a piezoelectric film (101) having a surface (111) including a halogen. In one embodiment, the halogen exists in an atomic concentration of at least approximately 10 percent. The result is a hydrophobic surface conducive to long-lasting scanning probe tips, low contamination, and stable surface charge. A data storage device incorporating the data storage medium includes an enclosure (205) containing the data storage medium and an adjacent scanning probe (230) wherein the enclosure has a relative humidity of at least approximately 40 percent and at least a portion of the scanning probe is coated with a layer of water.
