摘要： A method for recycling an optical disc in which the resin used in an optical disc (10) can be recovered easily with high purity. The method for recycling an optical disc comprises a polishing step and a circumferential surface removing step. In the polishing step, a recording surface (31) of the optical disc (10) on the side opposite to the reading surface (30) where the substrate part (11) is exposed is polished until the substrate part (11) is exposed. In the circumferential surface removing step, portions in the vicinity of the outer circumferential surface (32) and the inner circumferential surface (33) is removed from the optical disc.

摘要： A device for destructing signals stored on compact disk includes a base, a punching pin, and a push lever. The base has a top stub for engaging with a central hole of a compact disk positioned on the base, a through hole corresponding to a Start Lead In (SLD) area on the compact disk, and an L-shaped arm portion holding a spring mechanism. The punching pin is vertically movably mounted in the spring mechanism and aligned with the SLD area, and the push lever is pivotally connected at an end to one side of the arm portion for pushing against an upper end of the punching pin. When the push lever is pivotally pushed downward, the punching pin is driven downward to punch a hole on the SLD area and ruin lead-in signals recorded thereon, preventing data stored on the compact disk from being read and disclosed.

摘要： The foreign matter (P1,P2) adhered to the data bearing surface (2a,2b) of a master medium (2) is removed by use of a dry, non-contact removal process, so as to facilitate the performance of a high transfer quality magnetic transfer. Before performing a magnetic transfer or forming an optical disk, a magnetic transfer master medium or an optical disk master medium is placed in a vacuum chamber (3). The vacuum chamber is evacuated by an evacuating means (4), and a reactive gas is introduced thereto by a gas introducing means (6). In the state in which the chamber has been evacuated and the reactive gas has been introduced thereto, a discharging means (5) applies a discharge voltage in the chamber, causing a plasma discharge to be generated between the master medium (2) and an electrode (52). The plasma etching action of the plasma discharge burns off the foreign matter adhered to the surface of the master medium.

摘要： The invention relates to a method for processing data carriers, comprising the steps of supplying a batch of data carriers for processing, defacing the supplied data carriers and further processing the defaced data carriers, wherein during each step the quantity of data carriers of the batch is compared with a given quantity and a warning signal is generated if the thus determined quantity and the given quantity do not correspond. The invention further relates to a system for performing this method provided with a station for supplying data carriers, a station placed in series therewith for defacing the supplied data carriers and stations for further processing of the defaced data carriers placed in series with the defacing station, wherein the supply station and the defacing station are provided with means for determining a quantity of data carriers passing through the station, which quantity-determining means are connected to a control system. With the method and system according to the invention unsold data carriers, for instance CDs for which copyright payments have been refunded, can be destroyed in verifiable manner without the danger of these still being brought into commercial circulation.
