Abstract
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.
