<p>A data storage card (11) having spaced apart data strips (15 and 17). The card is wallet-size and preferably the strips run parallel to the lengthwise dimension of the card. One strip (15) is made of a high capacity reflective read-only optical memory (ROOM) material. The other strip (17) is a magnetic recording material. The high capacity ROOM strip may be made of a laser recorded material or it may be made of a material which is prerecorded using a photographic process. The two strips store complementary data in database applications.</p> |
