A method of testing an information recording medium includes a step of attaching an artificial fingerprint to an incident surface of an information recording medium, a step of reproducing a signal recorded in an attached region to which the artificial fingerprint has been attached, and a step of judging whether the information recording medium is defective or non-defective based on a signal quality of the reproduced signal. An information recording medium testing apparatus includes a fingerprint attaching unit that attaches an artificial fingerprint onto an incident surface of an information recording medium, a signal reproducing unit that reproduces a signal recorded in an attached region to which the artificial fingerprint has been attached, and a judging unit that judges whether the information recording medium is defective or non-defective based on a signal quality of the reproduced signal.
