A method for evaluating an anti-contamination level on a surface of
optical recording medium is disclosed. The method includes forming an
artificial fingerprint on the surface by contacting a stamp having an
artificial material adhered thereto on an optical recording medium, and
measuring a symbol error rate (SER) of the formed artificial fingerprint,
to determine a sensitivity of the fingerprint and determining whether the
optical recording medium is of good quality or bad quality depending upon
the measured SER.
