A media disc playing or recording arrangement comprises one of a complimentary pair of mats adapted to be placed adjacent the media disc as the media disc is inserted in a media disc player or recorder. The mat(s) comprise a lightweight film 1 of a conductive material preferably having a patterned layer 2 of one or more conductive inks printed thereon on one or both sides thereof (Figs. 1 to 3). One such mat has its material polarity at 0{ and the other mat at 180{, and, in the case of a compact disc or any other digital disc playing arrangement, the mats are of a size substantially corresponding to that of the digital disc, especially that of a compact disc. In the case of a vinyl record, the mats are of a size substantially corresponding to that of the record label at the centre of the record but without encroaching on the playing surface. The single mat to be used is selected from the pair dependant upon the material polarity of the media disc in use. The mat acts to counter the effect of any static or electrostatic charge that is built up on the surface of a disc whilst in use. |
