A media drive is disclosed. In one embodiment, a media drive can comprise:
a disk holder, a drive laser, a disk reader, and a luminescence detector.
The disk holder can be capable of applying a rotational force to a media
disk. The drive laser is disposed so that light from the laser will be
incident on the media disk when it is disposed in the disk holder. The
disk reader is disposed to receive data from the media disk. A method for
authenticating a media disk is also disclosed. The method can comprises:
disposing the article in a reader, illuminating at least a portion of the
article with the information reader, monitoring a luminescence emission
of the illuminated article, and determining if the luminescence emission
is consistent with an authentic article. If a luminescent material is
present, the information reader excites the luminescent material to
create a luminescence emission.
