A data sensing interface comprising a surface of a recording medium and a
tip of a data sensor positioned to sense data stored on the recording
medium and a layer of polyphenyl ether disposed between the tip and the
surface to function as a lubricant. A method of reducing wear within the
data sensing interface includes providing a layer of polyphenyl ether
between the tip of the data sensor and the surface of the recording
medium to act as a lubricant.
