Abstract
Embodiments for validating an optical disc storing protected content are provided. In one example, a method comprises receiving the optical disc in an optical disc drive, detecting with a signal detector a signal while the optical disc is at rest, spinning the optical disc, determining, with the signal detector, one or more of an electrical and magnetic effect on the signal resulting from the spinning of the optical disc, and validating the optical disc if the one or more of the electrical and magnetic effect meets a predetermined condition.
