Method and apparatus for evaluating degree of anticontaminau00e7u00e3o in optical recording medium, method for evaluating degree of anticontaminau00e7u00e3o in superfu00eccie of optical recording medium, optical recording medium.A method to evaluate the level of anticontaminau00e7u00e3o on the surface of the optical recording medium is disclosed.The method includes forming a fingerprint on the surface for contacting the artificial stamp having an artificial material adhered to the same in an optical recording medium.And measuring an error rate of symbol (be) of the artificial fingerprint is formed.To determine the sensitivity of the fingerprint and determine if the optical recording medium is good quality or bad quality depending on the to be measured.
