发明名称 METHOD FOR TESTING ANTI-CONTAMINATION OF DISK SURFACE
摘要 A method for evaluating stain resistance of a disk surface is provided to improve evaluation reliability by measuring an error rate in the area in which an adhered artificial fingerprint is formed. A method for evaluating stain resistance of a disk surface comprises the steps of: contacting a stamp, in which an artificial fingerprint material is adhered, to a disc and adhering the artificial fingerprint onto the disk surface at the set pressure(S60); measuring an error rate in the area in which the adhered artificial fingerprint is formed, where the error rate is the rate of error data blocks in data block of LDC(Long Distance Code)(S70); and determining sensitivity about the artificial fingerprint from the measured error rate.
