An optical disc apparatus according to the present invention includes: an optical pickup including an optical system that converges a light beam on an optical disc and a photodetector that detects light reflected from the optical disc; and a fingerprint detector for detecting, based on the output of the photodetector, multiple fingerprint dots on the surface of the optical disc. The fingerprint detector confirms the presence of a fingerprint on the optical disc on sensing the output of the photodetector change according to the pattern of the fingerprint dots.
