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.

摘要:
Disclosed is a method for authenticating that an article is an authenticatable article. The method uses an optical tester, the optical tester comprising an electromagnetic radiation source and a detector. The authenticatable article comprises a heat responsive compound having a temperature dependent optical interaction with the electromagnetic radiation source in the presence of a heat stimulus to produce a heat induced electromagnetic radiation signature. The method comprises placing a test portion of the article in interaction with the electromagnetic radiation source of the optical tester, creating a heated portion by exposing the test portion of the article to a heat stimulus sufficient to raise the temperature of the test portion from a temperature T1 to a temperature T2, measuring the heat induced electromagnetic radiation signature of the heated portion with the detector, and authenticating that the article is an authenticatable article if the heat induced electromagnetic radiation signature is present.
