DESCRIPTION:In the magnetic storage industry\, thin film carbon overcoats 
 play a critical role in reducing magnetic and physical spacing between the
  recording slider and the rotating disk so that the information stored per
  unit area is maximized.  \n\nThin film carbon overcoats have been improve
 d such that they exhibit higher hardness with lower thickness of few nanom
 eters and still are able to perform reliably.  \n\nIn this presentation\, 
 nanoindentation and nanoscratch techniques to measure nanomechanical prope
 rties\, namely hardness\, elastic modulus and shear strength of thin solid
  films will be presented along with a newly developed high resolution forc
 e transducer and a correction to the classic Oliver-Pharr nanoindentation 
 technique.  \n\nIt was shown that the properties and wear behavior of sub-
 10 nm thick film carbon overcoats were reliably measured. These techniques
  could be applied to different thin solid films on substrates\, and they a
 re not restricted to magnetic storage systems.  \n
