<p>The utility model relates to a card with a compact disk, which comprises a first rectangular substrate (4), a pit, a laser beam and a device for presenting patterns on the card surface. The central hole (1) of the card is encircled by an annular data recording area (3) which is arranged on the upper surface of the first rectangular substrate. The pit standing for data is arranged in the data recording area (3). A first metallic layer (5) is plated on the upper surface of the first rectangular substrate (4). The lower surface of the first metallic layer is at least covered with the data recording area (3). The laser beam is used for reflecting to penetrate through the first rectangular substrate (4) and reflect into the data recording area (3). The device used for presenting patterns can be the pit or a table. The pit or the table are positioned in the data recording area (3), and are combined into patterns, and can change shapes.</p> |
