An optical disc player discriminates an attribution of tracks recorded onto a disc inserted in the player, and normally reproduces MP3 tracks recorded onto discs inserted into a plurality of disc drivers using an MP3 decoder. Each of the first and second plastics materials is comprised of at least 25% by weight, based on the total weight of the base layer and the connection layer, respectively, of polyolefins, while the third plastics material has a proportion, based on the total weight of the buffer layer, of more than 75% by weight of a thermoplastic elastomer which is not a polyolefin. The X-ray irradiatingdetecting device is rotated about the object in order to acquire transmission X-ray data stemming from a plurality of views. The tool and method may be used to displace insulation adjacent the lead end of the inner conductor or outer conductor to facilitate connection of the connector.
