The invention relates to a digital data carrier (1) with a carrier body (2) whose profile deviates from the standard outer diameter. The inventive digital data carrier is for playing in a standard CD-drive (6) which has a retractable tray (5) with a first receiving element (15) for data carriers with a larger standard diameter and a second receiving element (13) for data carriers with a smaller standard diameter. The digital data carrier has a centring aid on the side of the carrier body facing towards the tray, for centring in the second receiving element (13). Said centring aid consists of two ring pieces located opposite each other and adapted to the second receiving element (13). |
