Abstract:
1. An anti-copy prevention system, comprising: a chipless RFID disk having a print layer distributed with metal fibers; an Optical Disk Drive (ODD) reading recorded information when mounted with the chipless RFID disk; and a reader installed in the ODD to sense whether the metal fibers distributed at the printed layer exist and to sense a unique ID contained in the metal fibers, wherein the chipless RFID disk comprises: a substrate having a first region and a second region; a reflecting layer formed on the first region of the substrate; and a protective layer formed on the reflecting layer, wherein a central area of the substrate has a through hole formed therethrough, wherein the second region is a surrounding area of the through hole, wherein the print layer is formed on the second region of the substrate, wherein a first side surface of the print layer is in direct physical contact with a first side surface of the reflecting layer and a first side surface of the protective layer, wherein the first side surface of the print layer comprises a first part contacted with the first side surface of the reflecting layer and a second part contacted with the first side surface of the protective layer, wherein a second side surface of the print layer is exposed to an outside by the through hole, wherein a top surface of the print layer is exposed to an outside, wherein a bottom surface of the print layer is in direct physical contact with a top surface of the substrate, wherein the first region is a recorded region and the second region is an unrecorded region, and wherein the first side surface of the print layer, the first side surface of the reflecting layer, and the first side surface of the protective layer are a boundary line between the first region and the second region.
