Abstract

"MéTODO E APARELHO PARA AVALIAR NìVEL DE ANTICONTAMINAçãO EM MEIO DE GRAVAçãO óTICA, MéTODO PARA AVALIAR NìVEL DE ANTICONTAMINAçãO NA SUPERFìCIE DE MEIO DE GRAVAçãO óTICA, MEIO DE GRAVAçãO óTICA". Um método para avaliar nível de anticontaminação na superfície de meio de gravação ótica é revelado. O método inclui formar uma impressão digital artificial na superfície por contatar o carimbo tendo um material artificial aderido ao mesmo em um meio de gravação ótica, e medir uma taxa de erro de símbolo (SER) da impressão digital artificial formada, para determinar a sensibilidade da impressão digital e determinar se o meio de gravação ótica é de boa qualidade ou má qualidade dependendo do SER medido.
